Stormproof material is the most waterproof yet breathable car cover material available. The micro-fiber base material is soft to the touch and won't scratch a car's paint, yet rolls up into a very compact package for easy storage.
Stormproof accomplishes the needs of a premium car cover material without coatings which can easily wear off, treatments which fade over time, and processing which can be undone the first time it is exposed to water. Stormproof is immune to this because it is inherently water resistant. The fibers have been designed to reflect UV rays, and be immune to the color fading caused by the harsh sun. Stormproof will last for years, and compliment your vehicle with exciting colors.
