When the arms are tired from long reaches, it's time for a harness. Mystic say...

The Wingman is our wing foil harness, ideal for longer distances as a lightweight design with simple padding. It sits comfortably around the waist and leaves the rider with plenty freedom of movement. Featuring a selflocking webbing strap, and a leash on the back to attach your board. The injection molded slider hook can hold up to 400kg and slide to either side while you paddle. 

Sizes available XS/S, M/L , XL/XXL.
