The Pro-Lite 7mm Freesurf 6'-10' Leash functions best in small, medium, and overhead wave conditions. The neoprene ankle cuff is comfortable to move in, and you can trust the 7mm cord to stand up to a variety of conditions. A stainless steel double swivel minimizes tangling while standing up to salt water, and a detachable rail saver protects your board when necessary.
