Early season grouse hunters and quail hunters asked that we make them lighter in weight and more breathable so we constructed these of single-layer, middle-weight denier nylon. We added a longer 22″ side zipper so you can open them for ventilation or to take them off with your boots on. They feature the same belt loops with snaps as our waterproof chaps. These chaps do a good job of busting brush and all but the heaviest briars. Keep a pair in your vehicle and be ready to hunt or train in an instant. Proudly made in the USA by American small businessmen and women!
