The ProTech's body is made of three breathable layers. Outer layer is nylon for durability. Middle layer is perforated neoprene for support. Inner layer is a soft jersey for comfort. Rugged molded shells are strategically placed for protection of the inner splint area, the tendon area, and the fetlock area. Constructed with darts for a close, clean fit and bound with lycra to keep the dirt and debris out. Fastened with a simple but secure, easy on/ off system of hook-and-loop straps.
