Fangs, thorns and briars simply can not penetrate the double layers of 1000 Denier DuPont Cordura® nylon. The tough as nails fabric has a polyurethane, water resistant coating , so rain and heavy dew cant get through it either. Adjustable side straps with snaps make length adjustment simple. Heavy duty, non corrosive, 14" knee-to-ankle zippers make pulling the chaps on and off over boots a breeze. Sizes: Regular: 25" thigh/20" cuff, Husky: 28" thigh/23" cuff. Inseams: Short: 27"-30", Regular 30-33", Long 33"-36". Guaranteed snake-proof.
