This unique and versatile cover incorporates expandable windshield and backrest pockets to accommodate everything from a stock Road Star to a fully accessorized Silverado, yet maintains that custom-fit look. The top half uses premium Evolution 4™ fabric that is breathable, water repellent, and UV-resistant. The bottom half is constructed of duck canvas for heat protection against exhaust pipes. Both materials provide excellent outdoor protection. (Not recommended for trailering.)
