Snake Chapz FP provide full snake bite protection from ankle to thigh. Heavy shoes or boots (not tennis shoes or similar) are required for foot and ankle protection. These full protection chaps are stiff and a bit hard to walk in and therefore are recommended for working in snake infested swampy areas -- not for hiking or general outdoor recreation. They are designed with patented polycarbonate and acrylic inserts that have been puncture tested based on ASTM F1342.05 with no penetration. Material covering the inserts is made with 600 Polyester materials and a coating for water resistance and so fang venom does not soak into the material. The blaze orange color is the only color of this brand of snake chaps that is made from polyester. Polyester is used because nylon cannot be dyed the high visibility orange and still stay bright. Snake Chaps are to be worn over regular clothing. 100% Made in the USA!
