The Ultralite Cover is made with a 70-denier polyester with polyurethane and mildew-resistant undercoating for enhanced water resistance. It's not waterproof, but very close, so you will not have a wet butt after a rain shower. This material also has a treatment to prevent mildew. One sewn-in vent allows moisture to escape. Soft cotton protects the windshield. Elastic shock cord is sewn into the front and back of the cover. Includes storage bag. Two-year limited manufacturer's warranty. Grey, L, Fits Touring Bikes
