This is a stretch-type stash bag that allows you to fold and store your wing. Downwinding with both hands free is the best! You can see how it's used in a video by searching for "Downwinding with Parawing in Hashigui". - During upwind, turn the bag around and use it as a harness belt. - Before downwinding, switch front and back. - Store the wing during downwinding. It fits even longer bars (GONG is 44cm) without any problems. It can store wings up to approximately 5m². It's also useful for getting past shore breaks. Good as a bag for spare wings too. For wing foil harness hooks, please use the 38mm (1.5 inch) belt type. I also have other wing equipment such as harness hooks and belts for sale.
