Zippy Sacs manufactures the Zippy Bike Sac, which is a totally self-contained enclosure. When opened it will completely cover a road or mountain bike while rooftop racked. The Zippy Snowboard Sac is a multi-functional product that converts from a fanny-pack into a fully functional snowboard sac as an all in one, radical package. The Zippy Wheel Sac is a versatile, contoured and padded enclosure designed for maximum use to protect any bicycle wheel. We utilize urethane coated 420 and 600 denier pack cloth with only the finest zippers and hardware. Every sac design is engineered to the highest of standards and put through rigorous testing in our R&D department. We are proud that our products are handcrafted in the U.S.A.
