The Pro-Lite Comp Surfboard Leash is designed for small to medium wave surf. With a 5.5mm cord thickness, these leashes are both light and tough. A good option for those average days. Features include double stainless swivels to keep the leash spinning smoothly and a recessed horn to reduce the pull on your ankle. Worried about somebody watching you hide your key in the rocks? Stash it in the hidden ankle cuff key pocket.
