The waterproof garment includes a first segment of a laminated composite material, a second segment of the laminated composite material, and a seam joining the first and the second segments of the laminated composite material to form the garment. The seam includes a light curable adhesive. ## Claims ### Claim 1 A waterproof breathable garment comprising: a first segment of a laminated composite material; a second segment of said laminated composite material, wherein said laminated composite material comprises a first fabric layer, a second fabric layer, at least one membrane layer laminated between said first and second fabric layers, and at least one carbon layer laminated between said first and second fabric layers; and a seam joining said first and said second segments of said laminated composite material to form said garment, said seam comprising a light curable, water proof, adhesive, wherein said seam does not include a seam tape. ### Claim 2 (depends on 1) A waterproof breathable garment in accordance with claim 1 wherein said seam comprises an overlap seam, said overlap seam comprising a portion of said first segment overlapping a portion of said second segment, and said light curable adhesive positioned between said overlapping portions of said first and second segments. ### Claim 3 (depends on 1) A waterproof breathable garment in accordance with claim 1 wherein a portion of said first segment is joined to a portion of said second segment by stitching forming said seam, said seam comprising said light curable adhesive positioned over a plurality of openings in said first and second segments formed by said stitching. ### Claim 4 (depends on 3) A waterproof breathable garment in accordance with claim 3 wherein said seam comprises a butt seam or an overlap seam. ### Claim 5 (depends on 1) A waterproof breathable garment in accordance with claim 1 wherein said light curable adhesive is an acrylate based adhesive or a urethane based adhesive. ### Claim 6 (depends on 5) A waterproof breathable garment in accordance with claim 5 wherein said light curable adhesive comprises a liquid or a film before curing. ### Claim 7 (depends on 1) A waterproof breathable garment in accordance with claim 1 wherein said light curable adhesive is curable from exposure to a visible light source emitting visible light having a wavelength of about 390 nm to about 410 nm. ### Claim 8 (depends on 1) A waterproof breathable garment in accordance with claim 1, wherein said membrane layer comprises a porous membrane layer having oleophobic properties. ### Claim 9 (depends on 8) A waterproof breathable garment in accordance with claim 8 wherein said porous membrane layer comprising at least one of expanded polytetrafluoroehtylene, woven polytetrafluoroehtylene, and non-woven polytetrafluoroehtylene. ### Claim 10 A method of making a waterproof breathable garment, said method comprising: providing a composite material comprising a first segment and a second segment, wherein the composite material comprises a first fabric layer, a second fabric layer, at least one membrane layer laminated between said first and second fabric layers, and at least one carbon layer laminated between the first and second fabric layers; and forming a seam joining the first and second segments of the composite material, the seam comprising a light curable, waterproof adhesive, wherein forming a seam does not include using a seam tape. ### Claim 11 (depends on 10) A method in accordance with claim 10 wherein forming a seam comprises: applying the light curable adhesive to a portion of the first segment; positioning a portion of the second segment so as to overlap the portion of the first segment so that the light curable adhesive is located between the portion of the first section and the overlapping portion of the second portion; directing an output of a high intensity visible light source at the seam to cure the light curable adhesive. ### Claim 12 (depends on 10) A method in accordance with claim 10 wherein forming a seam comprises: stitching a portion of the first segment to a portion of second segment; applying the light curable adhesive to the portion of the first segment to cover any openings formed by the stitching; directing an output of a high intensity visible light source at the seam to cure the light curable adhesive. ### Claim 13 (depends on 11) A method in accordance with claim 11 wherein forming a seam further comprises applying the light curable adhesive to the portion of the second segment to cover any openings formed by the stitching. ### Claim 14 (depends on 10) A method in accordance with claim 10 wherein the seam comprises a butt seam or an overlap seam. ### Claim 15 (depends on 10) A method in accordance with claim 10 wherein the light curable adhesive is an acrylate based adhesive or a urethane based adhesive. ### Claim 16 (depends on 15) A method in accordance with claim 15 wherein the light curable adhesive comprises a liquid or a film before curing. ### Claim 17 (depends on 11) A method in accordance with claim 11 wherein directing an output of a high intensity visible light source at the seam to cure the light curable adhesive comprises directing a visible light having a wavelength of about 390 nm to about 410 nm at the seam to cure the light curable adhesive. ### Claim 18 (depends on 10) A method in accordance with claim 10, wherein the membrane layer includes a porous membrane layer having oleophobic properties. ### Claim 19 (depends on 18) A method in accordance with claim 18 wherein the porous membrane layer comprises at least one of expanded polytetrafluoroehtylene, woven polytetrafluoroehtylene, and non-woven polytetrafluoroehtylene. ### Claim 20 A seam formed between two pieces of a multilayered textile material comprising a first fabric layer, a second fabric layer, at least one membrane layer laminated between the first and second fabric layers and at least one carbon layer laminated between the first and second fabric layers, said seam comprising a light curable adhesive, wherein the adhesive is not a seam tape.
