The Ocean and Earth SUP/Longboard Leash is the ultimate leash for your SUP or Longboard. The leash is made from diamond-flex urethane that allows for a controlled stretch. The double-padded ankle strap is lightweight, and creates a secure fit. The marine-grade anti-corrosive dual-anchor swivels allow for a tangle-free ride. The leash is 8mm in diameter, and allows for a wave size of 5ft for a SUP, and 8ft for a longboard.
