     FIELD 
     The disclosure relates to headwear including an elastic sizing mechanism. 
     BACKGROUND 
     Headwear, such as baseball-style caps, may include both fitted and adjustable variations. While fitted caps may be sized for a particular head dimension, adjustable caps provide at least some flexibility in sizing to fit differently-sized heads. An example adjustment mechanism for a cap includes a snapback mechanism which is often formed of a pair of plastic tabs that overlap and engage with one another when fastened. One of the tabs includes a plurality of protruding snaps while the other tab includes a plurality of holes for accepting the snaps. The snapback mechanism allows different head dimensions to be accommodated by engaging an outermost hole on one of the plastic tabs with different protruding snaps on the other of the plastic tabs. 
     SUMMARY 
     Embodiments are disclosed for headwear comprising a crown including a cap, and a size-adjusting mechanism extending around a portion of a perimeter of the cap and adapted to selectively adjust a size of the cap. The size-adjusting mechanism may comprise a first tab including a plurality of holes, and a second tab including a plurality of snaps configured to engage with the plurality of holes of the first tab, at least one of the first tab and the second tab being coupled to the perimeter of the cap via an elastic portion attached to a terminal end of a rigid portion of that tab.

     DETAILED DESCRIPTION 
     As described above, adjustable headwear may include snapback mechanisms for selecting a desired circumference of a bottom portion of the cap that engages with a wearer&#39;s head (e.g., a sweatband region of the cap). However, the available sizes of other snapback headwear are bound by the number of holes that engage with snaps of the snapback mechanism and the spacings between the holes. In this way, a wearer may have to choose between a slightly loose and a slightly tight fit when wearing other snapback headwear. 
     In order to address the above-described issues and provide an increased granularity to the available sizes of headwear utilizing snapback mechanisms, the present disclosure provides an elastic snapback mechanism. The elastic snapback mechanism described herein enables a wearer to stretch one or both of the tabs used in the snapback mechanism in order to achieve a comfortably snug fit along a sweatband of the headwear. 
       FIG. 1  shows a side view of an example headwear, such as a hat or headwear  100 . As illustrated, headwear  100  includes a visor  102  and a crown  104 . The visor  102  may be attached to, extend from, and/or otherwise be carried by the crown  104  (e.g., a bottom portion of the crown  104 ). The crown may comprise a cap configured to extend over a top of a wearer&#39;s head. In some embodiments, the crown  104  may include a plurality of panels extending around a circumference of the crown and intersecting at a central region (e.g., affixed to a button  106  on the top of the crown). In other embodiments the crown  104  may be formed of a single panel or piece of fabric (e.g., a unibody construction) forming any suitable hat body shape. In some embodiments, each panel (or the entirety of the crown/visor) may include the same type of fabric or other material. In other embodiments, one or more panels (or the crown) may include a different type of material than the other panels (or the visor). 
     A headband  202  may extend around at least a portion of the circumference of the crown  104  (e.g., along a bottom edge of the crown, away from the button  106 ). The headband  202  may form another panel of the crown  104  and/or a junction between the crown and the visor  102 . The headband may extend around at least a portion of the circumference and/or perimeter of the base of the crown (e.g., leaving an opening  206  in the back of the crown) and house at least a portion of a sizing mechanism  204 . For example, headband  202  may be formed from a substantially rectangular panel that includes terminating ends that are spaced from one another and/or that terminate at tabs of the sizing mechanism  204 . The size of the hat may be adjusted by pulling the terminating ends closer to one another (or farther apart) using sizing mechanism  204 , which may also adjust a size and/or shape of the opening  206 . 
       FIG. 2  shows a rear view of headwear  100  of  FIGS. 1 and 2  including a more detailed view of sizing mechanism  204 . Sizing mechanism  204 , as illustrated, may form an elastic snapback mechanism. Sizing mechanism  204  includes two tabs: a first tab  208  that includes a plurality of holes  210 , and a second tab  212  that includes a plurality of protruding snaps  214 . The snaps  214  may be sized to engage with holes  210  in a secure manner. For example, the snaps  214  may include a top having a larger diameter than a post from which the top extends. The holes  210  may be formed of a material that is flexible enough to allow the holes to expand and/or stretch slightly to allow passage of the top when the top is inserted into the holes by pressing tabs  208  and  212  together, then constrict under the top to hold the snap in place until a force is applied to pull the tab  208  away from the tab  212 . 
     As shown, the tabs  208  and  212  may extend into a headband region of the headwear  100 . For example, the headband  202  may include material that is folded upward from the crown  104  to form a pocket between the headband  202  (e.g., which is configured to come into contact with a wearer) and the outer region of the crown  104 . In other embodiments, the headband  202  may be sewn to the crown  104  to form the above-described pocket. One or more of the tabs  208  and  212  may attach to, extend from, and/or otherwise be carried by a) the surface of the headband  202  that is configured to contact the wearer, b) an interior of the above-described pocket formed between the headband and the outer portion of the crown, and/or c) an exterior of the crown (e.g., away from the headband  202  and away from the wearer&#39;s head. Although illustrated as occupying a substantially central region of the back of the headwear  100  and/or opening  206 , the sizing mechanism may be positioned in other locations in some embodiments. For example, tabs  208  and  212  may be positioned to a side of the opening or off-centered within the opening when engaged with one another (e.g., when one or more snaps  214  are positioned within associated holes  210 ). 
       FIG. 2  also shows a detailed view of example internal structures and attachment locations for an elastic sizing mechanism of headwear  100 . As illustrated, tabs  208  and  212  may include portions comprising different materials. For example, the portions that engage with one another within the opening  206  may form a first rigid portion that is formed of substantially rigid or non-elastic material. It is to be understood rigid, as used herein, refers to materials that are less elastic than elements described herein as elastic. For example, a substantially hard plastic may still flex and bend, but may not stretch (e.g., along a perimeter of the headwear  100 ). An elastic portion may include portions of the tabs that attach to the crown  104  in  FIG. 2 . In contrast to the rigid portions of the tabs, the elastic portions stretch along a perimeter of the headwear  100 . 
     As used herein, the term elastic may refer to the elastic characteristic of the material used in the elastic portion. For example, an elastic portion may include any suitable object or material that is able to resume its normal (e.g., unstretched/resting) shape spontaneously after contraction, dilation, or distortion (e.g., stretching). Elastic portions may include any suitable cord, tap, or fabric, which may be woven with strips of rubber or other elastic/elastomeric materials, and/or other material(s)/composite(s) having the features described above that returns to its original length or shape after being stretched. In some examples, elastic portions may include tape made of plastic or other materials that form a flat, smooth, and/or non-rounded strip that may lie flat with the hat and/or follow contours of the hat such that there are no protrusions that may cause discomfort to a wearer. 
     In  FIG. 2 , the attachment points  402   a  and  402   b  of the elastic portions of tabs  208  and  212 , respectively, are substantially equally distant from a center of the opening  206 . In other words, the attachment points  402   a  and  402   b  may be equally distant from an edge ( 404   a  or  404   b ) of the opening  206  on an associated side of headwear  100 , where the sides of the hat are approximately separated from one another along axis  406  which extends through the center of opening  206 . In other embodiments, the distance between the attachment points  402   a / 402   b  of the elastic portions and the center of opening  206  may be different for each attachment point. In such examples, the rigid portion of the tabs  208  and  212  that engage with one another may be off-center with respect to the opening  206  or the elastic portions of tabs  208  and  212  may have different lengths from one another. It is to be understood that attachment or coupling, as used throughout the disclosure, may refer to any suitable coupling mechanism, including but not limited to attaching, stitching, gluing, adhering, chemical bonding, sewing, etc. Particular coupling mechanisms may be performed to provide advantages relating to that coupling mechanism, and disclosure of a particular coupling mechanism to join two or more elements together may be understood to also cover the disclosure of any other suitable coupling mechanism to join those two or more elements together. 
     The attachment points  402   a  and  402   b  may include one or more attachment mechanisms. For example, the elastic portions of the tabs may be attached to the crown and/or headband via stitching, gluing, grommets, magnets, and/or any other suitable mechanical or chemical fastening mechanism. Although only one attachment point is shown for each tab  208  and  212 , it is to be understood that the elastic and/or rigid portions of the tabs may be attached to the crown and/or headband via two or more attachment points. It is to be further understood that any of the above-described attachment mechanisms may be used in any combination to provide the attachment points for each of the tabs. 
     As shown at  408   a  and  408   b , the tabs  208  and  212 , respectively, may include a rigid spine. The rigid spine may be another rigid portion of the tabs that is configured to provide structural support for the corresponding elastic portion of that tab. The rigid spines  408   a  and  408   b  may include a rectangular strip of rigid material having a plurality of protrusions spaced from one another and extending from the rectangular strip toward a bottom and a top of the headwear. The rigid spines  408   a  and  408   b  may be encased in and/or integrated with a portion of the elastic portion of the respective tabs  208  and  212 . For example, the elastic material may be overmolded over the rigid spines such that the elastic material is adjacent to all surfaces of the rigid spines, thereby integrating the rigid spines into the elastic material. The rigid spines may extend from an attachment point of a first rigid portion of the respective tab (e.g., the rigid portion that is exposed and/or configured to engage with the rigid portion of the other tab) to the elastic portion of the respective tab, and may terminate prior to reaching an attachment point of the elastic portion of the respective tab to the crown  104  and/or headband  202 . The rigid spines may include one or more holes for increased flexibility and to allow the elastic material to attach to an increased surface area of the rigid material, creating further chemical and mechanical bonds between the two materials. Although each tab is illustrated as including a rigid spine, it is to be understood that in other embodiments, only one tab or neither tab may include a rigid spine. 
     It is to be understood that the rigid spines may have any suitable arrangement, shape, position, etc. For example, one or more rigid spines may be positioned at any region along the length of the elastic portion of a tab (e.g., closer to an opening in the crown, closer to an attachment point of the tab to the hat/headband, in a center of the tab, etc.) and/or along a height of the elastic portion of the tab (e.g., closer to the top of the tab, closer to the bottom of the tab, at a center of the tab, etc.). If both tabs of the hat include a spine, the spine(s) of one tab may be located in a different region of that tab than the spine(s) of the other tab. In additional or alternative non-limiting examples, a plurality of spines may be distributed next to each other along a length of a tab (e.g., spaced from one another or adjacent to one another with contacting surfaces) and/or distributed above/below each other along a height of the tab (e.g., spaced from one another or adjacent to one another with contacting surfaces). In further additional or alternative non-limiting examples, one or more spines of a hat may have different structural features, such as irregularly spaced/sized protrusions from a center of the spine, dimples or detents in regions of the spine, spikes or jagged edges along the spine, rough and/or smooth material along different regions of the spine, etc. In some non-limiting examples, the material used in the spine may differ in different regions of the spine. The spine may also have different thicknesses in different regions of the structure. As a non-limiting example, protrusions of the spine may be thinner than a center of the spine. It is to be understood that other example configurations of rigid material may be provided to form the spines described herein. 
       FIG. 3  shows an isometric view of a bottom of headwear  100 . As illustrated, attachment point  402   a  is located between an edge of the opening  206  and an edge  502  of the visor  102  (e.g., a location at which the edge of the visor intersects with the crown  104 ). In other examples, the respective elastic portion of each of the tabs may be configured to extend along less than half of the circumference of the perimeter of the crown. For example, the elastic portion of tab  208  may attach to the crown and/or headband/sweatband along one or more points in attachment region  504 . In this way, the elastic portion of tab  208  may extend from the rigid portion of tab  208  to any location along the perimeter of the crown  104  between the opening  206  and the edge  502  of visor  102 . In other examples, the attachment region may extend to occupy approximately half of the perimeter of the crown  104 . It is to be understood that the elastic portion of tab  208  may extend from the rigid portion of tab  208  to any location along the perimeter of the crown in some examples, including but not limited to extending all of the way around the perimeter to another rigid portion of a tab on the opposite side of opening  206  from tab  208 . The perimeter of the crown may also include multiple sections of material having different properties, each section of material joined to another section of material at different regions along the perimeter. For example, elastic portion of tab  208  may attach to the crown and/or headband/sweatband along one or more points in attachment region  504 , and another region of elastic material may extend between two additional points along the perimeter of the crown. 
       FIGS. 4A-4B  show example elastic snapback sizing mechanisms  600   a  and  600   b . In  FIG. 4A , a first tab  602   a  includes a rigid portion  604   a  with a plurality of holes for engaging with a second tab  603   a . First tab  602   a  also includes an elastic portion  606   a  (e.g., an elastic strap) extending from an attachment point  608   a  at which the elastic portion  606   a  is joined to the rigid portion  604   a . Second tab  603   a  includes a rigid portion  605   a  and an elastic portion  607   a , which join at an attachment point  609   a.    
     In  FIG. 4B , tabs  602   b  and  603   b  include two rigid portions each—the first rigid portion  604   b / 605   b , which engages with the other first rigid portion of the other respective tab, and second rigid portion  606   b / 607   b  (e.g., a rigid spine), which does not engage with the other tab. The tabs also include respective elastic portions  608   b / 609   b.    
       FIGS. 5 and 6  show an example snapback mechanism  700  positioned off-centered from a rear of a hat and including a sheathed elastic portion. As illustrated therein, the snapback mechanism  700  includes a first tab  702  and a second tab  704 . The first tab  702  includes a rigid portion  706   a , which includes a plurality of holes for engaging snaps of the second tab  704 . Attached to a terminal end of the rigid portion  706   a  is an elastic portion  708 . In this example, the elastic portion  708  comprises an elastic strip (e.g., a rectangular elastic strip of material) sheathed and/or housed within a rigid and/or less elastic material (e.g., fabric). The sheathing material is configured to accommodate the length of the elastic strip when the elastic strip is stretched (e.g., when stretched to a maximum length of the elastic strip). Accordingly, while the elastic strip is not stretched (e.g., to the maximum length), the sheathing material gathers or bunches around the elastic strip. 
     The second tab  704  only includes a rigid portion  706   b , which is attached to an outer surface (e.g., away from a wearer when worn) of the crown  710 . The rigid portion  706   b  includes a plurality of snaps configured to be inserted and secured within holes of the rigid portion  706   a  of the first tab  702  when the sizing mechanism  700  is in a locked position. As illustrated, the second tab  704  only occupies a region of the hat on one side of opening  712  in the crown  710 , and does not extend within the opening  712 . 
     The elastic portion  708  of the first tab  702  may be positioned such that it is sandwiched between an outer portion of the crown  710  of the hat and a headband/sweatband  802  (shown in more detail in  FIG. 6 ). For example, the elastic portion  708  passes through a pocket formed between the crown  710  and the headband/sweatband  802 . For example, the elastic portion  708  may extend around the perimeter of the crown  710  to the side of opening  712 , but may be at least partially obscured by the crown on the outer region of the hat and the headband/sweatband on the inner region of the hat. 
       FIGS. 5 and 6  show the tabs of snapback mechanism  700  in an example unlatched (e.g., unsecured to one another) configuration.  FIG. 5  shows an unlatched first tab  702 . In some examples, the elastic portion  708  includes two terminal ends opposite of one another. A first terminal end  902  of the elastic portion  708  is attached to a terminal end of rigid portion  706   a . In the illustrated example, both the elastic strip within the sheathing material and the sheathing material itself is attached to the terminal end of the rigid portion  706   a . A second terminal end  904  of the elastic portion  708  is attached to the hat between the crown and the headband/sweatband. As illustrated, the second terminal end  904  is attached a short distance from an edge of opening  712  of the crown  710 . However, it is to be understood that the second terminal end  904  may be attached directly to the edge of the opening  712  and/or any suitable distance from the edge of the opening  712  (e.g., extending up to halfway around the perimeter of the crown  710  and/or between the edge of the opening and an intersection of a visor of the hat and the crown on that side of the hat). It is to be further understood that the attachment point on the elastic portion  708  may not be positioned at the edge of the second terminal end  904 . For example, a small amount of the elastic portion  708  (e.g., less than 5% of the total length of the elastic portion when the elastic is not stretched) may extend past the attachment point of the elastic portion  708  to the hat. The attachment point may include an attachment to the crown  710  and/or the headband/sweatband  802 , and multiple attachment points may be provided in some examples. 
       FIG. 6  shows a rear view of unlatched first tab  702  and an unlatched second tab  704 . The unlatched second tab  704  includes two terminal ends opposite of one another. A first terminal end  1102  includes an outermost snap  1103 , which may be utilized to provide the largest hat/crown size when the outermost hole  1105  of the first tab  702  is secured thereto (e.g., in a latched configuration). In the illustrated example, the first terminal end  1102  is positioned at an edge of opening  712  in crown  710 . A second terminal end  1104  of the second tab  704  is positioned at a point along a perimeter of crown  710  away from opening  712 . Accordingly, in the illustrated example, the second tab  704  is positioned on one side of the opening  712  and does not extend past the opening  712 . It is to be understood that in other examples, one or both of the terminal ends of a second tab may extend past the edge of the opening  712  (e.g., toward an opposite side of the opening). 
     As the second tab  704  is positioned to the side of the opening  712 , the second tab  704  may be attached to the hat (e.g., to the crown  710  and/or the headband/sweatband  802 ) in multiple locations. For example, both the first and second terminal ends  1102  and  1104  may be attached to the crown  710 . In other examples, the entire length of the second tab  704  may be attached to the crown (e.g., by stitching, adhesives, and/or other attachment mechanisms that span the length of the tab and/or a circumference/perimeter of the tab). Any suitable number of attachment points and/or portion of the second tab  704  may be attached to the hat. While the second tab is illustrated as facing an outer surface of the hat (e.g., attached on the outer surface of the crown  710 ), in other examples, the second tab  704  may be attached to an inner surface of the hat. For example, the second tab  704  may be rotated such that the snaps extend into an interior of the hat (e.g., opposite of the illustrated direction), and the second tab may be secured to an inner surface (e.g., a wearer-side surface) of the headband/sweatband  802 . Such an arrangement may enable the snapback mechanism to be hidden on an interior of the hat. As such an arrangement may cause the snapback mechanism to directly contact a wearer&#39;s head, a moveable flap of material or other covering mechanism may be added over the mechanism to allow access to the snapback mechanism during adjustment while providing a barrier between the mechanism (e.g., the rigid portions of the mechanism) and the wearer. 
       FIG. 7  shows an example snapback mechanism  1200  including elastic portions disposed in a pocket between a headband/sweatband and an exterior of a crown of a hat.  FIG. 7  shows an interior view of a first tab  1202  of the example snapback mechanism  1200 . In  FIG. 7 , a rear view of a rigid portion  1204  of the first tab  1202  is illustrated as extending past a terminal end of a headband/sweatband  1206  and an edge of crown  1208 . In the illustrated example, the rigid portion  1204  extends partly between a pocket formed between the crown  1208  and the headband/sweatband  1206 . 
     In an unextended state, an elastic portion of the first tab  1202  may be housed between the crown  1208  and the headband/sweatband  1206 . In the illustrated example, the elastic portion does not extend past an edge of the crown  1208 . The headband/sweatband  1206  may be attached to the crown  1208  along a bottom perimeter of the crown  1208  so as to create a pocket housing the elastic portion of the first tab  1202 . 
       FIG. 7  also shows an unextended elastic portion of a second tab  1402  of the example snapback mechanism. The second tab  1402  includes a rigid portion  1304 , which extends partly into a pocket formed between the headband/sweatband  1206  and the crown  1208  (e.g., at an opposite terminal end of the headband/sweatband than the first tab  1202 ). The second tab  1402  also includes an elastic portion  1306 , which is fully housed in the pocket between the headband/sweatband  1206  and the crown  1208  in an unextended state. When force is applied to pull the elastic portion  1306  of the second tab  1402 , the elastic portion may extend beyond an edge of the crown  1208  and outside of the pocket formed between the headband/sweatband  1206  and the crown  1208 . 
     The example elastic snapback mechanisms disclosed herein provide an increased granularity to the available sizes of headwear utilizing snapback mechanisms by allowing wearers to stretch the tabs of the snapback mechanism in order to achieve a comfortably snug fit along a sweatband of the headwear. Such modifications of the traditional snapback mechanism preserve the overall ease of use, adjustability, and appearance of that headwear adjustment mechanism while providing the comfort of an elastic headband. 
     The above examples largely incorporate snapback adjustable sizing mechanisms for hats. However, it is to be understood that the elastic adjustment mechanisms described therein may be applied to any other suitable adjustable sizing mechanism.  FIGS. 8A-11C  provide example alternative elastic adjustment mechanisms that may include elastic features as described above and below. In each example, one or more ends of the sizing mechanism may be provided with an elastic overmold, which includes an elastic material overmolded over a rigid or less elastic material (e.g., a material having a lower elasticity than the elastic material). In this way, the elastic material provides for comfort and fine adjustment of the mechanism, while the rigid or less elastic material provides for anchoring, guiding, and/or strengthening the mechanism. 
       FIGS. 8A-8C  show example pullable tab elastic adjustment mechanisms.  FIG. 8A  is a rear view of an example headwear, such as a hat  1600  including a pullable tab elastic adjustment mechanism  1602 . The mechanism  1602  may be positioned similarly to the snapback mechanisms described above. For example, although shown substantially centered in the rear of the hat  1600 , mechanism  1602  may be attached such that one or more tabs/straps extend toward a side of the hat (e.g., as shown in  FIG. 6  with regards to the snapback mechanism). Mechanism  1602  may include a fixed strap  1604  and a pullable strap  1606 , as well as a loop  1608 . Fixed strap  1604  may be substantially fixed (e.g., attached via any suitable mechanism, such as glued, sewn, stapled, stitched, and/or otherwise secured) to the hat  1600  at a first end (e.g., secured to a headband of the hat) and coupled to the loop  1608  at a second end opposite the first end. In some examples, the fixed strap  1604  may be formed as a folded strap, such that one of two terminating ends of the folded strap (the two terminating ends being opposite one another along the longest dimension of the strap) is passed through the loop  1608  and the two terminating ends are fastened to the headband of the hat (e.g., in an interior of the hat). 
     Similarly to the fixed strap, the pullable strap  1606  may have two terminating ends (e.g., opposite one another along the longest dimension of the strap), one of which is substantially fixed (e.g., attached via any suitable mechanism, such as glued, sewn, stapled, stitched, and/or otherwise secured) to the hat on an opposite side of an opening in the crown  1614  from the attachment point of the fixed strap  1604 . The other terminating end of the pullable strap  1606  (e.g., which is not fixed to the hat) may be passed through the loop  1608  and pulled to adjust a size of the hat. For example, all or a portion of the pullable strap  1606  may include hook and loop or other removable fastening material to allow one terminating end of the pullable strap to be pulled toward or away from the other terminating end to increase or decrease an overall/effective circumference of the headband. In other examples, the non-fixed terminating end of the pullable strap  1606  may include a button or other fastener that may be attached to one or more other points on the hat to maintain an adjusted circumference of the headband after pulling the non-fixed terminating end a desired extent. The pullable strap  1606  may include a tab  1610  to assist in pulling the non-fixed terminating end of the strap. 
       FIG. 8B  is a detailed view of the adjustment mechanism  1602 . As illustrated, the adjustment mechanism further includes spines  1612   a  and  1612   b . The illustrated shape of the spines is exemplary, as any suitable rigid or semi-rigid structure overmolded with an elastic material (e.g., a material more elastic than the spine) may be utilized as the spine. For example, one or both of the straps  1604  and  1606  may include an elastic overmold such that elastic material is chemically and mechanically coupled (e.g., bound) to the associated spine. The spines  1612   a  and/or  1612   b  may provide a rigid structure to assist the associated strap with maintaining a desired shape and provide strength as the straps are adjusted to change a size of the hat. The spines may also guide movement of the straps in the longitudinal direction when pulled in order to prevent twisting of the straps. In some examples, one or both of the straps  1604  and  1606  may be attached to respective elastic straps overmolded over respective spines, such that the elastic straps permit additional movement of the one or both straps  1604  and  1606 . In such examples, the straps  1604  and/or  1606  may be attached to the hat via the additional elastic straps. In other examples, the straps  1604  and/or  1606  may be attached directly to the hat and via the additional elastic straps in a reinforced manner. 
     Although a single spine is illustrated in each of fixed strap  1604  and pullable strap  1606 , it is to be understood that one or more spines may be included in one or both of the straps  1604  and  1606 . For example, a single spine may be included in fixed strap  1604  and no spine may be included in pullable strap  1606  or vice versa. In other examples, one or both straps may include multiple spines. The spines may be positioned in any suitable location and extend for any suitable length to provide the structural support described above. In some examples, spines  1612   a  and  1612   b  may correspond to rigid spines  408   a  and  408   b  of  FIG. 2 . Accordingly, spines  1612   a  and  1612   b  may include any one or more of the features of rigid spines  408   a  and  408   b  described above with respect to  FIG. 2 .  FIG. 8C  shows an isometric view of hat  1600 . One or both straps may include the same material as the crown of the hat (e.g., as an outer covering; other material, such as a hook and loop material for pullable strap, may be used for an interior region of the strap). 
       FIGS. 9A-9C  show example hook and loop elastic adjustment mechanisms in accordance with one or more embodiments of the present disclosure.  FIG. 9A  is a rear view of a hat  1700  including a hook and loop elastic adjustment mechanism  1702 . The mechanism  1702  may be positioned similarly to the snapback mechanisms described above. For example, although shown substantially centered in the rear of the hat  1700 , mechanism  1702  may be attached such that one or more tabs/straps extend toward a side of the hat (e.g., as shown in  FIG. 6  with regards to the snapback mechanism). Mechanism  1702  may include a fixed strap  1704  and a pullable strap  1706 . Fixed strap  1704  may be substantially fixed (e.g., attached via any suitable mechanism, such as glued, sewn, stapled, stitched, and/or otherwise secured) to the hat  1700  at a first end (e.g., secured to a headband of the hat) and free (in an unfastened condition) or attached to the pullable strap  1706  (in a fastened condition) at a second end opposite the first end. The pullable strap  1706  may be arranged similarly to the fixed strap  1704  (e.g., fixed to the hat at one end and free/fixed to the fixed strap  1704  at an opposite end), and may include a tab  1710  to facilitate adjustment of the strap (e.g., pulling it toward the fixed end of the fixed strap  1704  to tighten the hat). An interior surface of the pullable strap  1706  may be configured to be in face-sharing contact with an exterior surface of the fixed strap  1704  to maintain a desired headband circumference (e.g., to change a distance between regions of the headband that terminate at an opening of crown  1714  of hat  1700 ). Accordingly, the interior surface of the pullable strap and the exterior surface of the fixed strap may include hook and loop material (e.g., one surface including hook material and one surface including loop material). It is to be understood that other fastening mechanisms may be used, such as buttons, adhesive, and/or other suitable fasteners in order to join the surfaces together. 
     Similarly to the pullable strap adjustment mechanism described above with respect to  FIGS. 8A-8C , one or both of the straps  1704  and  1706  may include elastic material overmolded over rigid or semi-rigid spines  1712   a / 1712   b , as illustrated in  FIG. 9B .  FIG. 9C  shows an isometric view of hat  1700 . One or both straps may include the same material as the crown of the hat (e.g., as an outer/inner covering; other material, such as a hook and loop material, may be used for an interior/exterior region of the strap). 
       FIGS. 10A-10C  show example buckle elastic adjustment mechanisms in accordance with one or more embodiments of the present disclosure.  FIG. 10A  is a rear view of a hat  1800  including a buckle elastic adjustment mechanism  1802 . The mechanism  1802  may be positioned similarly to the snapback mechanisms described above. For example, although shown substantially centered in the rear of the hat  1800 , mechanism  1802  may be attached such that one or more tabs/straps extend toward a side of the hat (e.g., as shown in  FIG. 6  with regards to the snapback mechanism). Mechanism  1802  may include a fixed strap  1804  and a pullable strap  1806 . Fixed strap  1804  may be substantially fixed (e.g., attached via any suitable mechanism, such as glued, sewn, stapled, stitched, and/or otherwise secured) to the hat  1800  at a first end (e.g., secured to a headband of the hat) and free (in an unfastened condition) or attached to the pullable strap  1806  (in a fastened condition) at a second end opposite the first end. The pullable strap  1806  may be arranged similarly to the fixed strap  1804  (e.g., fixed to the hat at one end and free/fixed to the fixed strap  1804  at another part of the strap). Each of the fixed strap  1804  and the pullable strap  1806  may include a portion of a buckle  1808  (e.g., at a terminating end of the fixed strap  1804  and along the length of the pullable strap  1806 , respectively). The portions of the buckle on each strap may be configured to connect to one another in a fastened condition, as illustrated in  FIG. 10A . The portion of the buckle  1808  included in the pullable strap  1806  may include a loop through which a terminating end of the pullable strap  1806  may be passed and pulled to tighten the hat (e.g., to change a circumference of the headband of the hat by changing a distance between regions of the headband that terminate at an opening of crown  1814  of hat  1800 ). 
     Similarly to the pullable strap adjustment mechanism described above with respect to  FIGS. 8A-8C , one or both of the straps  1804  and  1806  may include elastic material overmolded over rigid or semi-rigid spines  1812   a / 1812   b , as illustrated in  FIG. 10B .  FIG. 10C  shows an isometric view of hat  1800 . 
       FIGS. 11A-11C  show example ballistic elastic adjustment mechanisms in accordance with one or more embodiments of the present disclosure.  FIG. 11A  is a rear view of a hat  1900  including a ballistic elastic adjustment mechanism  1902 . The mechanism  1902  may be positioned similarly to the snapback mechanisms described above. For example, although shown substantially centered in the rear of the hat  1900 , mechanism  1902  may be attached such that one or more tabs/straps extend toward a side of the hat (e.g., as shown in  FIG. 6  with regards to the snapback mechanism). Mechanism  1902  may include a fixed loop structure  1904  and a pullable strap  1906 . Fixed loop structure  1904  may be substantially fixed (e.g., attached via any suitable mechanism, such as glued, sewn, stapled, stitched, and/or otherwise secured) to the hat  1900  to provide a series of loops that may accept a hook  1908  disposed on the pullable strap  1906 . The pullable strap  1806  may be fixed to the hat at one end and free (in an unfastened condition) or fixed (in a fastened condition) to the fixed loop structure  1904  at another part of the strap. The pullable strap  1806  may be pulled toward the fixed loop structure  1904  and the hook inserted into a selected loop of the fixed loop structure to tighten the hat (e.g., to change a circumference of the headband of the hat by changing a distance between regions of the headband that terminate at an opening of crown  1914  of hat  1900 ). 
     Similarly to the pullable strap adjustment mechanism described above with respect to  FIGS. 8A-8C , the pullable strap  1906  may include elastic material overmolded over one or more rigid or semi-rigid spines  1912 , as illustrated in  FIG. 11B .  FIG. 11C  shows an isometric view of hat  1900 . 
       FIGS. 12A and 12B  show different views of an example headband  2000  including an elastic sizing adjustment mechanism  2006 .  FIG. 12A  shows an isometric view of the headband  2000 . The headband  2000  may include any combination of components and materials to form an adjustable crown-sizing feature of a hat. For example, headband  2000  may include a sweatband  2002 , having two terminating ends that are each attached to a respective strap  2004  (e.g., via a flange, as described in more detail below with respect to  FIGS. 15-17 ). The straps  2004  may be further attached to a sizing mechanism  2006 . The illustrated example shows a snap-back sizing mechanism, such as that described in  FIGS. 2-4B , but it is to be understood that any suitable sizing mechanism may be incorporated in the headband  2000 , including but not limited to those described above with respect to  FIGS. 8A-11C . Although shown as single elements, it is to be understood that sweatband  2002  and straps  2004  may include multiple sections and/or may be formed of composite materials. In some examples, sweatband  2002  may not extend fully between straps  2004 , but rather may include two or more sweatband sections that are attached to an interior of a crown of a hat. It is to be understood that headband  2000  may be incorporated into any suitable hat, including but not limited to those specifically described herein. 
     As illustrated in  FIG. 12A , sweatband  2002  may be attached to strap  2004  at one or more attachment points  2008 . The attachment points  2008  may include any suitable fastening mechanism, including but not limited to those specifically described herein. For example, as described in more detail below, a terminating end of sweatband  2002  may be inserted into a slot formed between outer and inner surfaces of a terminating end of strap  2004  and stitching may be passed from the outer surface of the terminating end of the strap, through the sweatband, and through the inner surface of the terminating end of the strap to secure the sweatband in the slot. In other examples, the slot may be lined with glue or other adhesives to secure the sweatband therein. In still other examples, the sweatband may be mechanically secured in the slot (e.g., mechanically clamped, such that protruding features within the slot are pressed through the sweatband). 
     The straps may be attached at an opposite terminating end (e.g., opposite to the terminating end that is attached to the sweatband) to a rigid structure and/or other feature of sizing mechanism  2006 . The straps  2004  may be attached to the sizing mechanism  2006  in any suitable manner, including but not limited to those described above with respect to attaching the straps to the sweatband. In some examples, the same mechanism may be used to attach the strap to both the sweatband and the sizing mechanism. In other examples, different mechanisms may be used to attach the straps to the sweatband and the sizing mechanism.  FIG. 12B  shows a front view of headband  2000 , including attachment points  2010  at which the straps  2004  are attached to the sizing mechanism  2006 . 
       FIG. 13  shows an example view of overmolding within an example headband  2100  of a hat. For example, spine structures  2102  and  2104 , which may be formed similarly to rigid spines  408   a  and  408   b  of  FIG. 2 , may extend from tabs of a sizing mechanism  2106  and attachment points  2108 , respectively. Straps  2110  may include elastomeric material overmolded over the spine structures  2102  and  2104  to form an elastic copolymer overmold. Attachment points  2108  may connect the sizing mechanism  2106  (e.g., via straps  2110 ) to a region of a hat (e.g., a sweatband of a hat or other material in a perimeter portion of a crown of the hat), which may be formed of any suitable material. As discussed above with respect to rigid spines  408   a  and  408   b , the overmolding may promote structural integrity near points of attachment to control a direction of elastic stretching and retain a shape of the headband. 
       FIG. 14  shows an example detail view of overmolding within an example elastic member  2200 . Elastic member  2200  may include an elastomeric strap  2202  including one or more spine structures  2204   a  and optionally  2204   b  extending from attachment points  2206 . As shown by the dashed lines, spine structure  2204   b  is optional and may be omitted in examples where only one end of the elastic member  2200  is to be reinforced. For example, the terminating end at attachment points  2206  of the elastic member that is closest to spine structure  2204  may be attached to a sizing mechanism, while the other terminating end at attachment point  2206  may be attached to a sweatband of a hat or may extend continuously around a perimeter of the hat in order to allow the elastic member  2200  itself to serve as the sweatband of the hat. In this example, spine structure  2204   b  may not be included, and the elastic member  2200  may only include one spine structure. In other examples, where reinforcement at both terminating ends is used, the elastic member  2200  may include both spine structures  2204   a  and  2204   b  near opposing terminating ends of the elastic member. In still other examples, one or more spine structures may be disposed at any suitable location(s) along the length of the elastic member  2200 . The above-described elements of elastic member  2200  may be similar to the likewise-named elements of headband  2100 , and the above-description of such elements may thereby apply to elastomeric strap  2202 , spine structures  2204 , and attachment points  2206 . As illustrated in  FIG. 14 , in some examples, strap  2202  may extend from one attachment point to another, without including a specific sizing mechanism there between. Strap  2202  may enable any two structures to be attached to one another via an elastic intermediary element by attaching to the two structures at respective attachment points  2206 . Accordingly, elastic member  2200  may be coupled to a sizing mechanism at one terminating end (e.g., via one attachment point  2206 ) and a headband or other hat feature at an opposite terminating end (e.g., via the other attachment point  2206 ). In another example, two sections of a headband may be attached to one another via the elastic member  2200 . The above examples are non-limiting, and any two elements may be joined via elastic member  2200  to allow the two elements to be elastically coupled to one another. 
       FIG. 15  shows a front isometric view of an example band  2300  including a double-sided sew flange for an elastic sizing mechanism or other suitable structure having multiple elements that are to be joined together. Band  2300  may include a first band section  2302  joined to a second band section  2304  via a double-sided sew flange  2306 . The first and second band sections  2302  and  2304  may include any suitable material or combination of materials. In one example, band section  2302  may include a terminating end of a sizing mechanism, which may be rigid or semi-rigid in some examples, and band section  2304  may include a terminating end of a headband of a hat. Flange  2306  includes a pair of slots  2308  with a buffer element  2310  disposed there between. A terminating end of each of the band sections  2302  and  2304  may be inserted into a respective slot  2308  (e.g., to a maximum depth that corresponds to contacting the buffer  2310 ). 
     Stitching  2312  and/or any other suitable securing/fastening mechanism may be utilized to secure/fasten the band sections within the respective slots. For example, the stitching may pass through holes  2314  and through the band sections to secure the band sections within the slot. In other examples, holes  2314  may represent a secondary securing mechanism (e.g., bolts/tacks or similar structures may be passed through the holes and the band sections to the other side of the flange). The holes  2314  may additionally or alternatively serve as indicators to guide insertion of stitches and/or other fastening mechanisms. In some examples, the flange  2306  may be at least semi-rigid to provide structural support for the band sections. In such examples, the flange  2306  may also be semi-flexible to promote comfort (e.g., when the flange is used to join material in a garment, such as a headband of a hat) and durability (e.g., to allow some give while the band sections move relative to one another). 
       FIG. 16  shows an example detail view of a long double-sided sew flange  2400  for an elastic sizing mechanism or other suitable structure having multiple elements that are to be joined together. As illustrated, flange  2400  may include two terminating ends  2402  that include slots  2404  formed within an opening between a front surface  2406  and a rear surface  2408  of the flange  2400 . As described above with respect to  FIGS. 12A-15 , two pieces of material that are to be joined may each be inserted into respective slots. In some examples, stitching, clamping, or other fastening mechanisms may be used to secure the material within the slots. Additionally or alternatively, the material may be secured within the slots due to a texture pattern of an interior of the slots and/or adhesive material disposed within and/or around the slots. The slots may form an “H” bracket or coupler and may include indicators for guiding application of stitching, clamping, or other fastening mechanisms. 
       FIG. 17  shows an example headband  2500  of a hat including a double-sided sew flange  2502  coupling a first material  2504  to a second material  2506 . As described above, the two joined materials  2504  and  2506  may comprise any suitable material, and may include material of a sizing mechanism and a headband, respectively, in some examples. Detail A of  FIG. 17  shows a close-up view of a slot  2508  of flange  2502 . As shown, a terminating end of each of the front surface  2510  and rear surface  2512  of the flange  2502  may be rounded in order to provide a gradual transition between the flange and the material  2506 . As shown, there may be a gap between the material  2506  and one or more regions of the interior of the slot. The gap may be filled with an adhesive and/or mechanically closed over the material by way of stitching, clamping, etc. In other examples, the gap (e.g., a gap between the two sections of material  2504  and  2506 ) may be maintained to allow additional stretching/movement during use. The size of the slot (e.g., the width, height, thickness, etc.) may be based on the material being inserted therein and/or may be a function of the overall width/height/thickness of the flange. Example dimensions of the flange may include ¾″ high (e.g., from a bottom to a top), 1-1.5″ wide (e.g., between terminating ends and/or between slot openings), with a slot opening that measures 25/1000″ between interiors of the front and rear surfaces of the terminating ends of the flange. It is to be understood that these measurements are exemplary in nature, and any suitable dimensions may be utilized. The flange may be made of any suitable material, including but not limited to polypropylene, nylon, polyethylene, and/or other soft-durable material. 
     In some examples, the flange may be a part of a kit or assembly for adapting a hat with an elastic sizing mechanism. For example, the kit or assembly may include the flange and one or both materials inserted therein. The material(s) may be attached to existing features of the hat to adapt the hat. For example, the material(s) may include a sizing mechanism and/or an elastomeric strap. Attaching these materials to one another and the hat via the flange enables the hat to be easily adapted to include an elastic sizing mechanism. In some examples, the flange itself may be formed of elastomeric material. In such examples, the flange may be attached to a rigid portion of a sizing mechanism via one slot and to a headband of a hat via another slot, the flange providing additional flexibility when using the sizing mechanism. 
     The disclosure above also provides for headwear including a crown including a cap, and a size-adjusting mechanism extending around a portion of a perimeter of the cap and adapted to selectively adjust a size of the cap, the size-adjusting mechanism comprising a first tab including a plurality of holes, and a second tab including a plurality of snaps configured to engage with the plurality of holes of the first tab, at least one of the first tab and the second tab being coupled to the perimeter of the cap via an elastic portion attached to a terminal end of a rigid portion of that tab.
