It's 32 miles across the Ka'iwi Channel, but the last few can make it feel like 320. Developed with long-distance paddleboard athlete Zeb Walsh, the lightweight R1 Short John is made from high-quality 1.5mm neoprene that meets our rigorous standards for performance, durability and warmth. The high-stretch 100% recycled polyester lining dries fast and offers excellent comfort and flex, while the open-arm design provides essential freedom of movement for long miles in open water. Streamlined anatomical patterning fits close to the body, and seams are sewn with flatlock construction for additional comfort and strength. Spandex binding at the neck and armholes is cleanly finished; exterior face fabric is 88% recycled polyester/12% spandex. 60-65° F/16-18° C.
