The Ultimate Shield cover provides all season indoor and outdoor protection for your vehicle. This nearly impenetrable fabric is fleece lined to protect fine automotive finishes and to ensure your vehicle’s surface finish stays in pristine condition. The Ultimate Shield has a special polypropylene, which is an oil based material, with a layer of micro-porous film sandwiched between it to ensure breathability. On the inside of the cover, there is a soft layer of fleece. Its high water resistance makes it weatherproof, yet breathable. The material is chemically treated to help prevent UV damage from the sun. Reduces heat based damage. Provides great protection against bird droppings. Protects against the effects of acid rain. Guards your vehicle from tree sap, dust, dirt, and other harmful pollutants. The fabric naturally resists rot and mildew. Its seams are ultrasonically welded. An elastic front and rear hem ensures a snug fit. There are reinforced grommets on both sides of the cover. \nWhy are there no side mirror pockets? Our car covers will accommodate your mirrors without pocketing them. We've engineered them out of the design because mirror pockets are unnecessary and are usually the first part of a car cover to deteriorate or rip. This ensures that you will get maximum durability from your car cover!
