Fun fact: Dakine was founded in 1979 with the production of the SUP Calf Leash, and it shows. This high-quality leash is made with 5/16-inch Dura-Cord for maximum strength, molded Opti-Flex leash ends for added durability, and a molded neoprene calf cuff for all-day comfort. Attach it to your board and you'll never be far from your favorite friend, no matter how many times you fall doing handstands.
