     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to odor absorbing clothing and, more particularly, to an article of clothing incorporating an odor absorbing substance. The odor absorbing substance is adapted to absorb odors emanating from the wearer and thereby reduce the chance that wildlife with an acute sense of smell will detect the wearer of the article. 
     2. Description of the Related Art 
     It is an unavoidable occurrence that humans emanate odors. The odors may originate from numerous sources including natural bodily secretions such as perspiration, oils, and the like; halitosis; colognes, perfumes, scented soaps, deodorants, shampoos, and the like; clothing worn by the individual; and odors that are absorbed by the individual&#39;s clothing and subsequently released to the surrounding environment. That a person emanates odors is not necessarily reflective of his personal hygiene but is simply an unassailable fact of human existence. 
     Numerous cosmetic and health care products have been developed to mask the more unpleasant odors. Colognes, perfumes, scented soaps, deodorants and the like which are employed for such purposes do nothing more than mask the undesirable odor and replace it with one that is considered more pleasing. In certain situations, however, it is desirable to provide an odorless or scentless presence. For example, certain people must have the ability to approach wild game in close proximity. Such persons include hunters, naturalists, wildlife photographers, wildlife biologists, wildlife political activists, and law-enforcement personnel charged with the responsibility of protecting wild game from injury, poaching and the like. 
     It is well known that wild game have a keenly developed sense of smell that can readily distinguish odors that are not indigenous to their natural habitat. Such odors may include those emanating from humans who attempt to gain close proximity to the game. Perfumes, scented soaps, and colognes may mask odors but are themselves readily detected by the wild game, perhaps at even greater distances. Such scents are not natural to the animals and therefore they are either scared away or alerted to the presence of potential danger. 
     One attempt to mask these odors is found in hunter&#39;s aids in the form of sponge-like pads that can be repeatedly impregnated with an artificially or naturally based aromatic scent such as deer lure. Examples of such devices are disclosed in U.S. Pat. No. 4,186,502, issued Feb. 5, 1982 to L. Foster and U.S. Pat. No. 4,302,899, issued Dec. 1, 1981 to G. DeHart. These devices function by distributing a scent that wild game find attractive but they do nothing to mask or absorb the odors emanating from the person. With time, the attractive powers of the lure diminish thereby decreasing its effectiveness. Moreover, the wild game may sense both the attractant and the odors emanating from the person. These prior devices are not acceptable because they do nothing to eliminate the scents indigenous to humans. 
     There has been a long-felt need for some device that is adapted to readily, efficiently and effectively absorb human odors such that a user presents a virtually odorless or scentless appearance, thereby enabling one to approach wild game in close proximity. 
     SUMMARY OF THE INVENTION 
     In one embodiment, the invention is directed to an article of clothing adapted to cover at least a portion of body, preferably at least one of the torso, the waist or the head of a person wearing the article. The article of clothing is air permeable and incorporates an odor absorbing substance. This odor absorbing substance is susceptible to reactivation through the act of washing and drying the article of clothing. Preferably, the article of clothing incorporates either a bright, highly visible color scheme such as hunter&#39;s orange or alternatively incorporates a camouflage color scheme on an exterior surface of the article of clothing. This article of clothing absorbs at least a portion of the odor emitted from the wearer of the article of clothing thereby reducing the chances of wildlife detecting the wearer through the sense of smell. 
     In a preferred embodiment, the odor absorbing substance utilized is activated charcoal. This charcoal can be in the range of 5 g/m 2  to 120 g/m 2 . 
     In another embodiment, the article of clothing is either water repellant or water resistant. Further, the article of clothing can comprise any number of different articles of clothing including a coat, a shirt, a one-piece bodysuit, a mask, a hat or a pair of pants. 
     In still another embodiment, the invention comprises a system for reducing detection of wildlife through the sense of smell comprising a first and a second article of clothing. The first article of clothing is adapted to cover at least one of the torso region or the groin region of the person wearing the article of clothing. The first article is air permeable and incorporates an odor absorbing substance in an amount sufficient to reduce the naturally occurring body odors of the person wearing the article of clothing. The second article of clothing is air permeable and also incorporates an odor absorbing substance in an amount sufficient to reduce the naturally occurring body odors of the person wearing the article of clothing. In this embodiment, the activated charcoal of the first and second articles of clothing, when worn by an individual, combine to reduce the odors emitting from the wearer and thereby reduce the chance of detection of the wearer by wildlife having an acute sense of smell. 
     In one embodiment, the second article of clothing comprises a mask. In yet another embodiment, the second article of clothing comprises a pair of socks. In still yet another embodiment, the second article of clothing comprises a hat. In another embodiment, the second article of clothing comprises a pair of gloves. Alternatively, in another embodiment the second article of clothing comprises a pair of pants. 
     Preferably, both the first and second article of clothing are air permeable. In one embodiment at least one of the first and second article of clothing is water repellant. In yet another embodiment, a camouflage color scheme is provided on at least one of the first and second articles of clothing. 
     Still yet another embodiment of the invention comprises an article of clothing adapted to cover the torso region of a person wearing the article of clothing. This article of clothing is air permeable and incorporates activated charcoal in an amount sufficient to reduce the wearer&#39;s naturally occurring body odors. This reduces the chances of wildlife detecting the wearer through the sense of smell. 
     In a preferred embodiment, this article of clothing has a camouflage color scheme provided thereon. The article of clothing can also be either water repellant or water resistant. 
     In yet another embodiment, the article of clothing is adapted to also cover the groin region of the wearer. Alternatively, the article of clothing can be adapted to cover at least a portion of the head of the wearer. 
     In one embodiment, the activated charcoal is incorporated into a base layer of the article of clothing intermediate the inner and outer surfaces of the base layer. In an alternative embodiment, the activated charcoal is provided on the outer surface of a base layer. In still yet another alternative embodiment, the article of clothing is formed from an outer layer and a base layer and the activated charcoal is provided intermediate the inner surface of the base layer and the outer surface of the outer layer of the article of clothing. 
     Preferably, the article of clothing is adapted to be worn as the outer most layer of clothing of the wearer. In one embodiment this article of clothing comprises a coat. In another embodiment this article of clothing comprises a one-piece bodysuit.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Turning now to the drawings and in particular to  FIG. 1 , a person  10  is shown in conjunction with several articles of clothing, each of which, as explained more fully below, when constructed in accordance with the invention is adapted to absorb odors emanating from the person. The particular articles of clothing illustrated in  FIG. 1  include a head covering  12 , a breath shield  14 , an upper body or torso cover  16 , a lower body cover  18 , gloves or mittens  20 , foot covers or socks  22 , and boot or shoe covers  24 . Similarly, articles such as backpacks  50  ( FIG. 6 ), fanny packs  52  ( FIG. 7 ) and the like may incorporate odor absorbing means to absorb the odors of the materials stored therein. 
     The head covering  12  is adapted to substantially cover the entire head of the person  10  as well as the neck region. Preferably, an open portion  26  is provided in order that the person  10  may see. The breath shield  14  may be incorporated directly into the head covering  12  by stitching or adhesive bonding or may be in the form of a separate article of clothing similar to surgical masks and the like employed by physicians. 
     The upper body cover  16  is adapted to cover the torso and waist regions of the person  10  as well as the arms and shoulders. Similarly, the lower body cover  18  is adapted to cover the waist and pelvic regions  10  as well as the legs. The upper and lower body covers  16 ,  18  may comprise individual articles of clothing that overlap in the area of the waist or may be in the form of a one-piece body suit. 
     The gloves or mittens  20  may be worn over the hands and preferably overlap those portions of the upper body cover  16  that envelop the arms of the wearer. Similarly, the socks may be worn over the feet of the individual  10  and function as foot covers. Finally, the boot or shoe covers  24  commonly known as “gators” may be adapted to be worn over clad feet and may be provided with heels, soles or the like if desired. 
     The individual articles of clothing may be sized to conform to the person wearing the clothing although it is preferred that they be made large enough to be capable of being worn comfortably by a person dressed in otherwise conventional clothing. The individual articles of clothing may be thermally insulated or made water-repellent or water-resistant if desired although this is not required to successfully practice the invention. Similarly, the articles of clothing may be provided with an appropriate camouflaging color scheme so that the person  10  wearing clothing constructed according to the invention may blend more readily into the surrounding environment. Alternatively, it may be desired to provide the articles of clothing with a bright and highly visible color so that the person  10  will be easily observable by other people such as hunters. 
     Each of the articles of clothing identified above has a substantially similar construction in cross section, which construction is shown in greater detail in  FIGS. 2-4 . To assist the description hereinafter, the reference numeral  28  in  FIGS. 2-4  identifies an article of clothing generally. It will be understood that the article of clothing identified generally in  FIGS. 2-4  by the reference numeral  28  may comprise any of the articles of clothing described hereinabove including the head covering  12 , the breath shield  14 , the upper body cover  16 , the lower body cover  18 , the gloves, mittens or hand covers  20 , the socks or foot covers  22 , the boot or shoe covers  24 , or a duffle or knapsack  56  ( FIG. 8 ). 
     In the embodiment illustrated in  FIG. 2 , the article of clothing  28  comprises an inner layer  30  and an outer layer  32  having enclosed there between means  34  for absorbing odors of the wearer. The odor absorbing means  34  may be in the form of fibers treated with or having incorporated therein activated carbon or charcoal. A suitable example of such odor absorbing means is commercially marketed under the name Garfil-615 by Purification Products Ltd. of Great Britain and distributed in the United States by FILTEREX, Inc. of Shippensburg, Pennsylvania. Preferably, the amount of activated charcoal is in the range of 5 g/m 2  to 120 g/m 2 . Alternatively, the odor absorbing means could be in the form of chlorophyll, baking soda, activated alumina, soda lime, zeolite, calcium oxide, potassium permanganate or a similar substance. As used herein, the term “absorb” and its cognates (e.g., absorbed, absorbing, and absorption) refers generically to the action of absorption and of adsorption for the means identified in this paragraph. 
     The inner and outer layers  30 ,  32  of the clothing article  28  may be similar or dissimilar and may comprise cotton, polypropylene, wool, felt, polyester, TYVEK® or GORE-TEX®, a laminate comprising polytetrafluoroethylene bonded to a suitable fabric and commercially marketed by W. L. Gore &amp; Associates, Inc., Newark, Del. The various materials for the inner and outer layers  30 ,  32  may be, non-woven, closely woven, comprise a fine mesh or be fabricated in some other suitable manner. The inner and outer layers  30 ,  32  may be secured to each other by stitching, quilting, needling or adhesive bonding at appropriate and conventional locations (not shown separately In the drawings) such as seams. 
     In one embodiment, the inner and outer layers  30 ,  32  may be in the form of a needled, non-woven polyester fabric, each layer having a weight of approximately 10 to 12 oz./sq. yd. and a thickness of approximately 1/16″. The odor absorbing means may be provided by a layer of Garfil 615 having a weight of approximately 10-12 oz./sq. yd. 
     Alternatively, as best shown in  FIG. 3 , the article of clothing  28  may be in the form of a foam of latex or other polymer  36  that has been impregnated with the odor absorbing means  34 , such as activated charcoal. Whatever materials are selected for the ultimate construction of the article of clothing  28 , the article should preferably be durable, flexible, abrasion resistant, easy to manufacture, nontoxic, nonflammable, and capable of carrying or retaining substantial amounts of the appropriate odor absorbing means  34 . 
     A further embodiment of the article of clothing is seen in  FIG. 4 . In this embodiment, a base material  40  has a layer of odor absorbing means  34  bonded to a first surface  42 . Preferably, the layer of odor absorbing means  34  is mounted on the outer surface of the base material, although mounting the odor absorbing means on the inner surface of the base material is acceptable. The odor absorbing means  34  may be mounted on the base material  40  by a “printing” process wherein the odor absorbing substance, such as activated charcoal, is mixed with a bonding agent and then printed on the base material  40  by a silk-screen printing process. An example of this process is disclosed in U.S. Pat. No. 4,510,193 to Blucher et al., issued Apr. 9, 1985. 
     The person  10  may choose to wear some or all of the articles of clothing described above and illustrated in  FIG. 1 . The degree of odor absorption increases as the surface area of the body of the person  10  covered by the articles of clothing increases. Thus, the most effective odor absorbing arrangement will comprise the head covering  12 , the breath shield  14 , the upper body cover  16 , the lower body cover  18 , the gloves or mittens  20 , the socks or foot covers  22 , and the boot or shoe covers  24 . Although effective odor absorption may be realized by wearing only some of the articles of clothing, the person  10  will preferably wear all of the articles of clothing described above to provide a more-or-less total-coverage body suit. 
     In warm weather climates, it may be desirable to cover only a portion of the person  10 .  FIG. 5  shows an alternative embodiment of the suit according to the invention. In this embodiment, the person  10  wears an upper body cover  44  and a lower body cover  46 . The upper body  44  cover is analogous to a short-sleeve shirt wherein the person&#39;s chest, torso, shoulders and underarms are covered. The lower body cover  46  comprises a pair of shorts which cover the pelvic or groin region and a portion of the legs of the person  10 . The embodiment seen in  FIG. 5  may be enhanced by adding one or more of the head covering  12 , the breath shield  14 , the gloves  20 , the foot covers  22  or the shoe covers  24 . 
     It may be desirable to provide additional odor absorbing means  34  for those articles of clothing adjacent to body parts that are more likely to emanate readily detectable odors such as the underarms and pelvic regions. In this case, an enhanced layer of the odor absorbing means can be mounted to the article of clothing  28  in the underarm or pelvic regions. For example, two layers of activated charcoal in the amount of 50 g/m 2  may be mounted one on top of the other to create a total of 100 g/m 2  for enhanced odor absorption in one or more sensitive areas. 
     The articles of clothing according to the invention may be worn as an outer layer of clothing, as an inner layer, or intermediate outer and inner layers of otherwise conventional clothing. 
     It has been found that activated charcoal used as the odor absorbing means  34  may be reactivated for numerous cycles of use. This reactivation can occur merely by washing and drying the article of clothing  28 . Washing and drying helps to remove impurities and foreign articles bonded to the activated charcoal. 
     Reasonable variations or modifications are possible within the spirit of the foregoing specification and drawings without departing from the scope of the invention which is defined in the accompanying claims.
