This lightweight but durable concertina-fold bag is ideal for preserving the mylar in the leading edge of your glider. Keeping your mylar in smooth condition will, at the very least, increase the resale value of your wing, and will help it to maintain its performance over time. With a full-length YKK zipper for easy in-out, a wide Velcro band and straps to compress and preserve the mylar at the leading edge, the Saucisse has everything you need and nothing you don’t… unlike its namesake.
