The present invention is a stockingfoot wader having a body portion and a pair of booties. The body portion of the wader is comprised of multiple pieces including a suspender assembly, a front pocket assembly, a chest piece, a back piece, a left upper leg piece, a right upper leg piece, a gusset (or crotch) piece, a left outer lower leg piece, a right outer lower leg piece, a left inner lower leg piece, a right inner lower leg piece and a pair of gravel guards. The chest piece, back piece, left upper leg piece and right upper leg piece are manufactured from three-layer laminated breathable waterproof fabric that is selected for maximum breathability. The left outer lower leg piece, a right outer lower leg piece, a left inner lower leg piece, and right inner lower leg piece are manufactured from four-layer laminated nylon breathable and waterproof fabric that is selected for maximum resistance to puncture and abrasion damage. The gusset is manufactured from three-layer laminated stretchable breathable and waterproof material that provides maximum range of movement for the legs when a wearer is walking. The gravel guards are manufactured from jersey-covered perforated neoprene, with the perforations reducing their weight.
Each bootie comprises a toe piece, an ankle piece and a sole piece. The toe piece is comprised of three layers of at least two different materials including an outer layer that comprises a waterproof breathable membrane, a middle layer that comprises an insulating and stretchable non-breathable material such as neoprene which has been modified with perforations or cut holes, and an inner layer comprised of either a second layer comprising a waterproof breathable membrane or a knit or woven jersey fabric material. The ankle piece and sole piece are comprised of an insulating and stretchable neoprene material that is covered on both sides with fabric backing. The inside surface of the bootie is treated with an antimicrobial agent to prevent odor.
The front pocket assembly 5 is comprised of three stacked layers of material, consisting of an outer layer 9 having a plurality of hexagonal-shaped holes 10, a water-permeable middle layer 11, and a water-permeable inner layer 12. The three layers 9, 11, and 12 are attached to each other and to the chest piece 6 by stitching around a portion of the outside edges of the three layers. Two front pocket openings 13 allow hand access into a pocket formed within the space between the middle layer 11 and the inner layer 12.
The material of the outer layer 9 is a patented, commercially available fabric named HEXGRID®, comprised of high-strength nylon, manufactured by 5.11, Inc. of Modesto, Calif. The outer layer 9 forms an attachment face for fishing accessories such as fly boxes, bear spray, etc., which may be removably attached to the outside of the front pocket assembly via the hexagonal holes 10. The hexagonal holes 10 are in the shape of regular hexagons, each having a side length of approximately 1.5 centimeters, and with a spacing between adjacent parallel sides of adjacent holes 10 of approximately 0.5 centimeter. The middle layer 11 of the front pocket assembly 5 is comprised of stretchable, highly permeable polymer mesh fabric. The inner layer 12 of the front pocket assembly 5 is comprised of a permeable woven polymer fabric.
As shown in
The bottom left edge of the chest piece 6 is adhered to the top edge of the left upper leg piece 17, and the bottom right edge of the chest piece 6 is adhered to the top edge of the right upper leg piece 18. The inside edges of the left upper leg piece 17 and the right upper leg piece 18 are adhered to the left and right edges, respectively, of the gusset piece 19. A portion of the bottom edge of the left upper leg piece 17 is adhered to the top edge of the left outside lower leg piece 20. A portion of the bottom edge of the right upper leg piece 18 is adhered to the top edge of the right outside lower leg piece 21. A portion of the bottom edge of the left upper leg piece 17 and the bottom left edge of the gusset piece 19 are adhered to the top edge of the left inside lower leg piece 22. A portion of the bottom edge of the right upper leg piece 18 and the bottom right edge of the gusset 19 piece are adhered to the top edge of the right inside lower leg piece 23. The front edge of the left outside lower leg piece 20 is adhered to the front edge of the left inside lower leg piece 22, and the front edge of the right outside lower leg piece 21 is adhered to the front edge of the right inside lower leg piece 23. The fabric pieces 17-23 are shaped so that the knee of the wearer is covered by four-layer, maximum durability material, while the back of the knee is covered with three-layer, flexible material. The top edge of a gravel guard 24 and a bootie 2 are adhered to the bottom edges of the left outside lower leg piece 20 and the left inside lower leg piece 22, and to the lower edges of the right outside lower leg piece 21 and the right inside lower leg piece 23. The bottom edges of the gravel guards 24 are not adhered to other pieces of material, and are therefore free to be pulled up or down over the tops of the booties 2 and wading shoes (not shown).
The middle layer 32 of the toe piece material 30 is comprised of a durable and resilient waterproof material such as rubber, latex, or synthetic rubber such as silicone, neoprene, nitrile, or latex, which has been modified by the addition of strategically cut or punched holes 33 that penetrate completely through the material of the middle layer 32. Although the hole shape or size is not critical, in the example shown in
In a first embodiment, the bottom layer 34 of the toe piece material 30 is comprised of a knitted or woven fiber material such as jersey fabric. The material of the bottom layer 34 is selected so as to provide moisture wicking, in order to transfer foot perspiration away from the foot, through the holes 33 of the middle layer 32, and out to the atmosphere through the breathable membrane of the top layer 31. In a second embodiment, the bottom layer 34 is comprised of a second layer of breathable composite material similar to the top layer material 31, rather than knitted or woven fiber material.
