The Outdoor Designs Perma gaiters utilise Gore-Tex fabric to provide waterproof and breathable protection for lower legs against mud, rain, and debris. They feature a full-length front zip closure secured with a storm flap to prevent moisture ingress. The design includes an adjustable underfoot strap, a hook-and-loop closure system, and a drawcord closure at the top to ensure a secure fit around the calf. The reinforced lower sections are designed to withstand abrasion from boots and rocks.
