THURSO SURF 4 feet PRO coiled bodyboard leash features double stainless steel swivels, preventing your leash from tangling and wrapping around your arms. The ¼''(7.2mm) thick high-strength urethane cord makes the leash sturdy and strong enough for surfing even with huge surge. The coiled design eliminates the leash dragging in water and avoids snagging submerged objects to protect you from falling off the board. High Density Neoprene padded 1.5" wrist cuff is ultra comfortable and won't slide around on your wrist with the help of the super-strong Velcro system. The leash comes complete with a leash plug to replace your existing one if required. Your satisfaction is 100% GUARANTEED! If there are any manufacture defects with your THURSO SURF Bodyboard Leash, let us know and you can get your item refunded or replaced with no question asked!
