The StormBlock™ Plus cover combines groundbreaking materials with American craftsmanship. This high-tech cover is treated with StormBlock™, a protective system that is designed to create a moisture-repelling barrier. When water comes in contact with this barrier it will bead up and roll right off. This cover offers ultimate outdoor protection from rain, snow, dirt, mud, tree sap, bird droppings and more. This cover is made from a woven RipStop polyester material that is lightweight and tear-resistant. The seams of the cover are ultrasonically welded together to prevent any moisture from penetrating through the cover. A soft inner lining is included to help protect your vehicle's paint from scratching. Built-in grommets allow you tie down the cover in windy weather conditions.
