Preparing for a particularly challenging expedition? Be sure to choose this strap for your gaiters! It prevents them from slipping, twisting, or riding up, thus protecting your legs from moisture and low temperatures. Plus, the gaiter straps are made of DuPont and Hypalon materials, which are resistant to extreme temperatures and chemicals. They're also lighter than neoprene, which is why they're also popularly used in the production of outdoor gear.
