Dowco Guardian Traveler 26015-00 Half-cover designed to be a lightweight cover to keep moisture and the sun's heat off your seats, dash and other essential parts of your bike. 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. Elastic shock cord is sewn into the bottom of the cover to provide a snug fit.
