SUP leashes keep paddlers safely connected to their paddleboards in case of a fall. These coiled leashes are meant to help you stay close to your board even in rough waters so your board doesn't get pulled out of your reach, leaving you stranded. The swivel feature can help prevent any tangling, and coils are meant to reduce drag. If you plan on using your SUP in rivers, surf, or water with a heavier current, it's recommended to pair a SUP leash with a quick released waist belt to allow paddlers to quickly disconnect themselves if needed.
