When it comes to protection, Rampage has you covered. These breathable covers repel water, but won't trap moisture as they protect your vehicle finish from sun, dirt, droppings, and other airborne pollutants that harm the paint - they are great indoors or out. Unique 4-layer non-woven polypropylene construction blocks harmful paint contaminants with a rugged Spun Bond outer layer attached to two melt blown middle layers of added protection and joined with a softer inner layer to produce a water resistant fabric that protects vehicle finish from the elements while maintaining breath-ability to avoid temperature and moisture build-up under the cover.
