This is an all-new design foil cover made from neoprene instead of canvas. The neoprene gives the cover some stretch so it makes for a better fit. The cover has been reinforced with nylon webbing in all the high wear points and has YKK zippers throughout so it will protect your foil for years to come. The wing portion of the cover features a side entry and will fit all Sky Ski wings as well as aftermarket (sit-foil) wings currently on the market. The strut portion can be put on so it zips down or up, depending on whether the foil is left in the board & tower or not.
