Enhanced Freedom While Riding
One of the biggest challenges in wing foil and foil surfing is maintaining unrestricted movement while staying safely connected to the board. The ION Core Coiled Knee Leash solves this issue through its ergonomic knee-mounted design.

The durable 7mm urethane cord provides excellent recoil resistance while maintaining flexibility and responsiveness in changing water conditions.
