Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This nonprovisional application claims priority to U.S. Provisional Patent Application Ser. No. 61/988,531, filed on May 5, 2014, which is hereby incorporated by reference in its entirety. 
    
    
     FIELD 
     The field of this disclosure relates generally to packs used to facilitate carrying a load by a user and, more particularly, to a pack having a one-piece, seamless bodyside liner to facilitate user comfort. 
     BACKGROUND 
     Conventional backpacks typically include a plurality of panels stitched together to cooperatively define an interior compartment adapted to store objects for transport in the backpack and include a pair of shoulder straps attached to one or more of the panels for carrying the backpack on a user&#39;s back. The interior compartment is often selectively accessible by moving a suitable fastening system comprising one or more suitable fasteners (e.g., a slide fastener, straps, hook and loop, snaps, buttons) between a closed position and an opened position. In addition to the interior compartment, known backpacks may also have interior and/or exterior pockets for holding additional objects for transport in the backpack. In some configurations, these pockets are selectively moveable between closed and opened positions using any suitable fastening system. In other configurations, the pockets are open and thus, not selectively closeable. 
     Known backpacks often have a liner or other suitable material that covers the portion of the backpack adapted to face the user during use. More specifically, the bodyfacing surface of the shoulder straps and the bodyfacing surface of one or more of the panels may include a liner adapted for placement against the user during use of the backpack. However, known liners comprise a number of segments (e.g., not a single-piece) and are stitched (i.e., not seamless) to the underlying structure. During use, the edges of these liner segments and the stitching can irritate the skin of the user. For example, if a runner is using such a backpack and wearing a relatively light weight shirt or no shirt, the edges of the liner segments and/or the stitching can rub against the skin of the user while he/she is running causing chaffing, abrasion, a rash, or other skin irritation. 
     In view of the above drawbacks, there remains a need for a backpack having a liner that inhibits skin irritation, such as chaffing, abrasion or rash, during use of the backpack while providing comfort, durability, moisture resistance, stain resistance, and odor resistance.

     DETAILED DESCRIPTION OF THE DRAWINGS 
     With reference now to the drawings,  FIGS. 1-5  illustrate one suitable embodiment of a pack of the present invention in the form of a backpack, indicated generally at  10 . The backpack  10  includes a back panel  12 , a top panel  14 , a bottom panel  16 , two side panels (for example, a right side panel  18  and a left side panel  20 ), and a front panel  22 . The panels  16 ,  18 ,  20 , and  22  cooperatively define at least one interior compartment (not shown) adapted to store objects (not shown) for transport in the backpack  10 . In the illustrated embodiment, the interior compartment can be accessed by moving the top panel  14  from a closed position ( FIGS. 1-5 ) to an opened position (not shown). The top panel  14  can be secured in the closed position using any suitable fastening system comprising one or more suitable fasteners (for example, buckles  28 ) as seen in  FIGS. 1 and 2 . It is understood that the any suitable fasteners (for example, a slide fastener, straps, hook and loop, snaps, buttons) can be used to secure the top panel  14  in the closed position. It is also understood that the interior compartment can be accessed in a different matter (for example, using a slide fastener to separate one or more of the panels  16 ,  18 ,  20 , and  22 ) without departing from some aspects of this disclosure. 
     As seen in  FIGS. 1-3 , each of the side panels  18 ,  20  include a side pocket  30 ,  32  for receiving objects (not shown). It is contemplated that the backpack  10  can have more or fewer pockets than illustrated herein. It is also contemplated the pockets  30 ,  32  of the backpack  10  can be secured or fastened using any suitable fastener, such as, elastomeric bands, slide fasteners, hook and loop, straps, buckles, buttons, and snaps. It is further contemplated that the backpack  10  can include pockets on other panels (for example, the front panel  22 ). 
     In one suitable embodiment, the panels  12 ,  14 ,  16 ,  18 ,  20 , and  22  are connected to each other by stitching and are formed from a sufficiently durable and compliant material. The material of the panels  12 ,  14 ,  16 ,  18 ,  20 , and  22  can be any suitable material, including but not limited to, nylon and polyester. Suitably, the material of the panels  16 ,  18 ,  20 , and  22  is relatively soft, durable, water resistant, odor resistant, and stain resistant. 
     With reference to  FIG. 2 , the back panel  12  of the backpack  10  includes a pair of shoulder straps  34  for carrying the backpack  10  on a user&#39;s back (not shown). It is contemplated that in other suitable embodiments the backpack  10  can be provided with a single shoulder strap  34  (for example, a sling bag, and a messenger bag). The backpack  10  also includes a handle strap  36  disposed between the back panel  12  and the top panel  14  for manually carrying the backpack  10  with a single hand or for hanging the backpack  10  (for example, on a suitable hook). 
     In the illustrated embodiment, each of the shoulder straps  34  includes a plurality of pockets  38  for receiving objects (not shown). More specifically, the illustrated backpack  10  has two pockets  44  on each of the shoulder straps  34  but it is understood that the shoulder straps  34  can have any suitable number of pockets or, in other suitable embodiments, be free of pockets. It is also contemplated that the pockets  38  of the shoulder straps  34  can be secured or fastened using any suitable fastener, such as, elastomeric bands, slide fasteners, hook and loop, straps, buckles, buttons, and snaps. As seen in  FIG. 2 , for example, one of the pockets  38  is selectively closeable using a slide fastener (or zipper) and another using hook and loop. 
     It is contemplated that the backpack  10  can have any suitable size and shape without departing from some aspects of this invention. In one suitable embodiment, the backpack  10  is configured for allowing the user significant movement (for example, running, jogging, hiking, biking, skiing, climbing) while wearing the backpack  10 . In such an embodiment, the backpack  10  is suitably light weight. For example, in one suitable embodiment, the backpack  10  is less than two pounds, more preferably less than one pound, eight ounces, and even more preferably less than one pound. 
     In one suitable embodiment, the backpack  10  can be configured to receive any suitable hydration container (not shown). For example, the backpack  10  can have one or more exterior water bottle pocket for receive a water bottle (for example, a 20 ounce or 26 ounce bottle with kicker valve available from Ultimate Direction of Boulder, Colo., U.S.A.) and/or an interior reservoir pocket for receiving a reservoir (for example, a 70 ounce or 100 ounce reservoir also available from Ultimate Direction of Boulder, Colo. U.S.A.). 
     With reference now to  FIGS. 2 and 6 , the backpack  10  further includes a one-piece, seamless bodyside liner, indicated generally at  40 , that lines (or covers) the back panel  12  and/or both of the shoulder straps  34  of the backpack  10 . Thus, during use, the seamless bodyside liner  40  is configured for direct face-to-face engagement with the user. Since the bodyside liner  40  is a single-piece of material and does not include any seams, the bodyside liner  40  is less likely to cause skin irritation (such as, but not limited to, chaffing, rashes, and abrasions). More particularly, the seamless bodyside liner  40  of the backpack  10  illustrated and described herein inhibits skin irritation during use of the backpack  10  especially high activity use involving significant movement by the user (for example, running, jogging, hiking, biking, skiing, climbing). 
     Referring to  FIG. 6 , the bodyside liner  40  is shown in a laid flat configuration. The bodyside liner  40  includes a body portion  42  for lining the back panel  12  of the backpack  10  and two strap portions  44  for lining each of the shoulder straps  34 . As mentioned above, the bodyside liner  40  is a single-piece of material. Thus, the two strap portions  44  of the bodyside liner  40  are integral with the body portion  42 . Alternatively, the body portion  42  and the two strap portions  44  may be separately attachable to the bodyside liner  40  and/or the backpack  10 . The bodyside liner  40  further includes a peripheral edge  46 . 
     The bodyside liner  40  can be made from any suitable material. Preferably, the bodyside liner  40  is relatively soft, durable, moisture resistant, stain resistant, and odor resistant. In one suitable embodiment, the bodyside liner  40  comprises a suitable mesh material  45  but it is understood that the bodyside liner  40  can include any suitable material without departing from some aspects of this disclosure. For example, one suitable mesh material is available from Duck San Co., LTD of Gyeonggido, South Korea under product number DS14-42. 
     In the illustrated embodiment, the bodyside liner  40  is attached (for example, by stitching) to the back panel  12  and shoulder straps  34  only along or adjacent the peripheral edge  46 . That is, the portions of the bodyside liner  40  inboard of the peripheral edge  46  are free from attachment to the underlying structure (for example, the back panel  12  and shoulder straps  34 ). As a result, the bodyside liner  40  is free from inboard seams and the only seam associated with the bodyside liner  40  is a peripheral seam attaching the bodyside liner  40  to the underlying structure, for example, the back panel  12  and/or the shoulder straps  34 . 
     In one suitable embodiment, an edge binding  47  is disposed about at least about a portion of the peripheral edge  46  of the bodyside liner  40 . In the illustrated embodiment, for example, the edge binding  47  is disposed about the periphery of the strap portions  44  of the bodyside liner  40 . As a result, the edge binding  47  trims the attachment of the bodyside liner  40  to the shoulder straps  34 . Moreover, the edge binding  47  is disposed about a portion of the body portion  42  of the bodyside liner  40 . More particularly, only part of the attachment between the bodyside liner  40  and the back panel  12  is trimmed by the edge binding  47 . It is understood, however, edge binding  47  can be used to trim more (including entirely) or less of the peripheral edge  46  of the bodyside liner  40 . It is further understood that in some suitable embodiments, the edge binding  47  can be omitted. In such an embodiment, the bodyside liner  40  can have a self-bound seam about the peripheral edge  46 . 
     It is contemplated that the bodyside liner  40  can be attached to the back panel  12  and/or shoulder straps  34  (or other portion(s) of the backpack  10 ) using any suitable method. That is, the bodyside liner  40  can be attached to the back panel  12  and/or shoulder straps  34  by any means known in the industry that utilizes a suitable mechanical attachment, such as, but not limited to, sewing, bonding, and coupling between two or more fabric layers to permanently bind them together. It is also contemplated that the entire bodyfacing surface of the bodyside liner  40  including along or adjacent the peripheral edge  46  can be seam free. Thus, the portions of the bodyside liner  40  facing the wearer (for example, the bodyfacing surface(s) of the liner  40 ) can be free from attachment to the underlying structure, such as the back panel  12  and shoulder straps  34 . For example, the bodyside liner  40  can be attached to the back panel  12  and/or shoulder straps  34  beyond the bodyfacing surface(s) of the bodyside liner  40  using, for example only, a sew-and-turn (or stitch-and-flip) technique as is known in the industry. 
     With reference still to  FIG. 6 , the illustrated embodiment of the backpack  10  further comprises an insert layer  48  underlying at least a portion of the bodyside liner  40 . The insert layer  48  is disposed between at least a portion of the bodyside liner  40  and the back panel  12  and/or the shoulder straps  34 . As seen in  FIG. 6 , the illustrated insert layer  48  comprises a body portion  50  and a pair of strap portions  52  separate from the body portion  50 . Alternatively, the pair of strap portions  52  can be integrated with the body portion  50 . The body portion  50  of the insert layer  48  underlies the body portion  42  of the bodyside liner  40 , and the strap portions  52  of the insert layer underlie the strap portions  44  of the bodyside liner  40 . It is contemplated that the insert layer  48  can be formed from a single-piece of material or a plurality of separate, discrete pieces. The insert layer  48  facilitates attaching the bodyside liner  40  to the backpack  10 . 
     Moreover, the insert layer  48  can be formed from any suitable material or combination of suitable materials. Preferably, the insert layer  48  is relatively soft, durable, moisture resistant, stain resistant, and odor resistant. In one suitable embodiment, at least a portion of the insert layer  48  comprises a suitable mesh material. In the illustrated embodiment, for example, the entire insert liner  48  is formed by the mesh material. In another suitable embodiment, at least a portion of the insert layer  48  comprises a suitable padding material (for example, ethylene vinyl acetate (or EVA) padding). In an embodiment, the body portion  42  of the bodyside liner  40  comprises a suitable mesh material, and the strap portions  52  of the insert layer  48  comprise a suitable padding material. In other suitable embodiments, the insert layer  48  can be, in whole or in part, any suitable foam, sponge, or other padding material including but not limited to EVA, PU, PE, designed to provide structure, support, pressure distribution and/or cushioning at the interface between the backpack  10  and the wearer. In another suitable embodiment, the insert layer  48  can be any fabric, flexible molded plastic or composite, or other manufactured structure which is able to conform on a majority but limited basis to the wearer&#39;s body in such manner that areas where the insert layer  48  does not conform such non-conforming portion is designed to enhance breathability and air flow between the user and the backpack  10 . It is also contemplated that is other suitable embodiments, the insert layer  48  can be eliminated or have any suitable configuration without departing from some aspects of this disclosure. 
     As shown in  FIG. 7 , it is contemplated that the backpack  10  illustrated in  FIGS. 1-6  can include a waistbelt  53  for releasably securing the backpack  10  around the user&#39;s waist. In one suitable embodiment, the waistbelt  53  is selectively adjustable such that the backpack  10  can be form fitted to the user&#39;s waist when the backpack  10  is worn. In one embodiment of the backpack  10  having a waist belt  53 , the bodyside liner  40  can be configured to cover the body-facing portions of the waist belt  53 . Thus, in such an embodiment, the one-piece seamless bodyside liner  40  lines (or covers) the back panel  12 , both of the shoulder straps  34 , and the waist belt  53 . 
       FIGS. 8 and 9  illustrate another suitable embodiment of a one-piece, seamless bodyside liner, indicated generally at  54  that is suitable for use with the backpack  10  seen in  FIGS. 1-5 .  FIG. 8  illustrates the bodyside liner  54  in laid flat condition and  FIG. 9  illustrates the bodyside liner  54  is a folded (or use) condition. The bodyside liner  54  is configured to line (or cover) the back panel  12  and/or both of the shoulder straps  34  of the backpack  10 . Thus, during use, the seamless bodyside liner  54  is configured for direct face-to-face engagement with the user. Since the bodyside liner  54  is a single-piece of material and does not include any seams, the bodyside liner  54  is less likely to cause skin irritation (for example, chaffing, rashes, and abrasions) during use of the backpack  10 . 
     As seen in  FIGS. 8 and 9 , the bodyside liner  54  includes a body portion  56  for lining the back panel  12  of the backpack  10  and two strap portions  58  for lining each of the shoulder straps  34 . As mentioned above, the bodyside liner  54  is a single-piece of material. Thus, the two strap portions  58  of the bodyside liner  54  are integral with the body portion  56 . Alternatively, the body portion  56  and the two strap portions  58  may be separately attachable to the bodyside liner  54  and/or the backpack  10 . 
     The bodyside liner  54  can be made from any suitable material. Preferably, the bodyside liner  54  is relatively soft, durable, moisture resistant, stain resistant, and odor resistant. In one suitable embodiment, the bodyside liner  54  includes a suitable mesh material  60  but it is understood that the bodyside liner  54  can include any suitable material without departing from some aspects of this disclosure. In this embodiment, the mesh material  60  includes a plurality of first areas  62  of mesh having a first weave configuration  64 , and a plurality of second areas  66  of mesh having a second weave configuration  68  that is different than the first weave configuration  64 . In the illustrated embodiment, the first areas  62  having the first weave configuration  64  includes a tight weave; and, the second areas  66  having the second weave configuration  68  includes a medium weave. Alternatively, the first weave configuration  64  may include a medium weave or a low/loose weave. Moreover, the second weave configuration  68  may include a tight weave or a low/loose weave. It is understood that the first and second areas  62 ,  66  of the bodyside liner  54  can have other characteristics that are different instead of or in addition to the weave. The first areas  62  and second areas  66  are configured to facilitate providing characteristics such as, but not limited to, comfort, durability, moisture resistance, odor resistance, and stein resistance for the bodyside liner  54 . 
     In the exemplary embodiment, the first areas  62  and the second areas  66  are configured in a sequential pattern  69  along the bodyside liner  54 . In an embodiment, the first areas  62  and the second areas  66  are configured in an alternating pattern with respect to each other. In one embodiment, the first areas  62  include a Y-shape applied to the body portion  56 . Alternatively, the first areas  62  and the second areas  66  can include any pattern. Moreover, the first areas  62  and the second areas  66  are configured to include a plurality of variety of shapes and sizes. 
     In the exemplary embodiment, the bodyside liner  54  may include the peripheral edge  46  and/or the edge binding  47  (shown in  FIG. 6 ).

For example, the backpack can have one or more exterior water bottle pocket for receive a water bottle (for example, a 20 ounce or 26 ounce bottle with kicker valve available from Ultimate Direction of Boulder, Colo., U.S.A.) and/or an interior reservoir pocket for receiving a reservoir (e.g., a 70 ounce or 100 ounce reservoir also available from Ultimate Direction of Boulder, Colo. U.S.A.). 
     With reference now to  FIGS. 14 and 15 , the backpack  70  further includes a one-piece, seamless bodyside liner, indicated generally at  94 , that lines (or covers) the back panel  72  and/or both of the shoulder straps  90  of the backpack  70 . Thus, during use, the seamless bodyside liner  94  is configured for direct face-to-face engagement with the user. Since the bodyside liner  94  is a single-piece of material and does not include any seams, the bodyside liner  94  is less likely to cause skin irritation (for example, chaffing, rashes, and abrasions). In other words, the backpack  70  illustrated and described herein inhibits skin irritation during use of the backpack  70  especially high activity use involving significant movement by the user (e.g., running, jogging, hiking, biking, skiing). 
     The bodyside liner  94  includes a body portion  96  for lining the back panel  72  of the backpack  70  and two strap portions  98  for lining each of the shoulder straps  90 . As mentioned above, the bodyside liner  94  is a single-piece of material. Thus, the two strap portions  98  of the bodyside liner  94  are integral with the body portion  96 . Alternatively, the body portion  96  and the strap portions  98  may be separately attachable to the bodyside liner  94  and/or the backpack  70 . The bodyside liner  94  further includes a peripheral edge  100 . 
     The bodyside liner  94  can be made from any suitable material. Preferably, the bodyside liner  94  is relatively soft, durable, moisture resistant, stain resistant, and odor resistant. In one suitable embodiment, the bodyside liner  94  comprises a suitable mesh material  101  but it is understood that the bodyside liner  94  can comprise any suitable material without departing from some aspects of this disclosure. For example, one suitable mesh material  101  is available from Duck San Co., LTD of Gyeonggido, South Korea under product number DS14-42. 
     In the illustrated embodiment, the bodyside liner  94  is attached (for example, by stitching) to the back panel  72  and shoulder straps  90  only along or adjacent the peripheral edge  100  ( FIGS. 14 and 15 ). That is, the portions of the bodyside liner  94  inboard of the peripheral edge  100  are free from attachment to the underlying structure (for example, the back panel  72  and shoulder straps  90 ). As a result, the bodyside liner  94  is free from inboard seams and the only seam associated with the bodyside liner  94  is the peripheral seam attaching it to the underlying structure, for example the back panel  72  and/or the shoulder straps  90 . 
     In one suitable embodiment, an edge binding  102  is disposed about at least about a portion of the peripheral edge  100  of the bodyside liner  94 . In the illustrated embodiment, for example, the edge binding  102  is disposed about the periphery of the strap portions  98  of the bodyside liner  94 . As a result, the edge binding  102  trims the attachment of the bodyside liner  94  to the shoulder straps  90 . Moreover, the edge binding  102  is disposed about a portion of the body portion  96  of the bodyside liner  94 . More particularly, only part of the attachment between the bodyside liner  94  and the back panel  72  is trimmed by the edge binding  102 . It is understood, however, edge binding  102  can be used to trim more (including entirely) or less of the periphery of the bodyside liner  94 . It is further understood that in some suitable embodiments, the edge binding  102  can be omitted. In such an embodiment, the bodyside liner  94  can have a self-bound seam about the peripheral edge  100 . In an embodiment, the insert layer  48  (shown in  FIG. 6 ) may be used with the bodyside liner  94 . 
       FIGS. 16-18  illustrate another suitable embodiment of a one-piece, seamless bodyside liner, indicated generally at  104  that is suitable for use with the backpack  70  seen in  FIGS. 10-15 . Alternatively, the bodyside liner  104  may be suitable for any type of backpack such as, for example, only, backpack  10  (shown in  FIGS. 1-6 ). The bodyside liner  104  is configured to line (or cover) the back panel  72  and/or both of the shoulder straps  90  of the backpack  70 . Thus, during use, the seamless bodyside liner  104  is configured for direct face-to-face engagement with the user. Since the bodyside liner  104  is a single-piece of material and does not include any seams, the bodyside liner is less likely to cause skin irritation (for example, chaffing, rashes, and abrasions) during use of the backpack  70 . 
     As seen in  FIGS. 16-18 , the bodyside liner  104  includes a body portion  106  for lining the back panel  72  of the backpack  70  and two strap portions  108  for lining each of the shoulder straps  90 . As mentioned above, the bodyside liner  94  is a single-piece of material. Thus, the two strap portions  108  of the bodyside liner  104  are integral with the body portion  106 . Alternatively, the body portion  106  and the strap portions  108  may be separately attachable to the bodyside liner  104  and/or the backpack  70 . 
     The bodyside liner  104  can be made from any suitable material. Preferably, the bodyside liner  104  is relatively soft, durable, moisture resistant, stain resistant, and odor resistant. In one suitable embodiment, the bodyside liner  104  comprises a suitable mesh material  109  but it is understood that the bodyside liner  104  can comprise any suitable material without departing from some aspects of this disclosure. In this embodiment, the mesh material  109  comprises a plurality of first areas  110  of mesh having a first weave configuration  112 , and a plurality of second areas  358  of mesh having a second weave configuration  116  that is different than the first weave configuration  112 . In the illustrated embodiment, the first areas  110  having the first weave configuration  112  includes a tight weave and the second areas  114  having the second weave configuration  116  includes a medium weave. Alternatively, the first weave configuration  112  may include a medium weave or a low/loose weave. Moreover, the second weave configuration  116  may include a tight weave or a low/loose weave. It is understood that the first and second areas  110 ,  114  of the bodyside liner  104  can have other characteristics that are different instead of or in addition to the weave. The first areas  110  and the second areas  114  are configured to facilitate providing characteristics such as, but not limited to, comfort, durability, moisture resistance, odor resistance, and stain resistance for the bodyside liner  104 . 
     In the exemplary embodiment, the first areas  110  and the second areas  114  are configured in a sequential pattern  118  along the bodyside liner. In an embodiment, the first areas  110  and the second areas  114  are configured in an alternating pattern with respect to each other. Moreover, the first areas  110  and the second areas  114  are configured to include a plurality of variety of shapes and sizes. In one embodiment, the first areas  355  include a Y-shape applied to the body portion  106 . 
     In the illustrated embodiment, the bodyside liner  104  is attached (for example, by stitching) to the back panel  72  and shoulder straps  90  only along or adjacent a peripheral edge  120 . That is, the portions of the bodyside liner  104  inboard of the peripheral edge  120  are free from attachment to the underlying structure (for example, the back panel  72  and shoulder straps  90 ). As a result, the bodyside liner  104  is free from inboard seams and the only seam associated with the bodyside liner  104  is the peripheral seam attaching it to the underlying structure, for example the back panel  72  and/or the shoulder straps  90 . 
     In one suitable embodiment, an edge binding  122  is disposed about at least about a portion of the peripheral edge  120  of the bodyside liner  104 . In the illustrated embodiment, for example, the edge binding  122  is disposed about the periphery of the strap portions  108  of the bodyside liner  104 . As a result, the edge binding  122  trims the attachment of the bodyside liner  104  to the shoulder straps  90 . Moreover, the edge binding  122  is disposed about a portion of the body portion  106  of the bodyside liner  104 . More particularly, only part of the attachment between the bodyside liner  104  and the back panel  72  is trimmed by the edge binding  122 . It is understood, however, edge binding  122  can be used to trim more (including entirely) or less of the periphery of the bodyside liner  104 . It is further understood that in some suitable embodiments, the edge binding  122  can be omitted. In such an embodiment, the bodyside liner  104  can have a self-bound seam about the peripheral edge  120 . Moreover, the insert layer  48  (shown in  FIG. 6 ) may be used with the bodyside liner  104 . 
     It is contemplated that the one-piece seamless bodyside liners  40 ,  54 ,  94 , and  104  disclosed herein can be adapted for packs other than backpacks without departing from some aspects of this disclosure. For example, the one-piece seamless bodyside liners  0 ,  54 ,  94 , and  104  can be adapted for hip packs, waist packs, fanny packs wherein the bodyside liner fully covers the body-facing portions of the respective pack.
