Surfing river rapids requires a special skillset and the equipment to do it safely. Of paramount importance is a board leash that won't get hung up on submerged rocks and branches. Our six-foot-long River Floating Leash features a ¼-inch (6.5mm), hollow Dura-Cord designed to float on top of the water, while our Easy Clip quick release with tether allows you to detach the leash from your board in the event it gets snagged on underwater debris. The 1.5-inch (40mm) molded neoprene calf cuff is reinforced with a hydrophobic webbing material, and our rugged Opti-Flex leash ends provide maximum durability under pressure. Plus, our 100% marine-grade stainless steel swivels are built for longevity, so you can keep riding the wave that never ends.
