The Budge Shield series of covers are made from a three layer waterproof material, which consists of an inside and outside layer of spun bond polypropylene with a waterproof film layer in the center. This cover is 100 percent waterproof and proven to protect against the heaviest rains. The Rain Barrier does not trap condensation like most waterproof covers. Instead, the Rain Barrier's micro-porous technology allows condensation to escape. This cover is suitable for outdoor and indoor use. Budge Semi-Custom sizing assures a snug and secure fit. Storage Bag Included for When Not Protecting Your Vehicle.
