The Superior StormBlock Car Cover is unlike any other car cover on the market. This car cover features StormBlock super hydrophobic technology that actively repels moisture. This cover creates a superior hydrophobic barrier that moisture cannot penetrate through. Once moisture makes contact with the cover it will simply bead up and roll away. This material is also stain resistant and virtually self-cleaning as dirt and debris will easily wipe away. A Grip Rite elastic hem helps keep the cover secure to your vehicle while built-in reinforced grommets keep the cover tie-down in windy weather conditions. The first of its kind this covers offers superior outdoor vehicle protection.
