The Procomp surf leash offers the maximum strength possible with minimal resistance for up to shoulder high surf. This everyday leash will keep your board safely attached with the least drag possible thanks to the strong 3/16-inch urethane Dura-Cord. Dakine's longtime history innovating surf leashes is apparent in the use of marine grade stainless steel swivels, a 1.5-inch molded neoprene cuff, and Opti-Flex leash ends which combine for a super efficient, comfortable and durable leash. 6' x 3/16'' (1,83m x 5mm). Material: Urethane, Stainless Steel.
