The culmination of more than 15 years of development, Stormproof material is the most water-repellent yet breathable car cover material available. The material exhibits outstanding sun and UV resistance, able to last for years in Arizona sun without fading. The microfiber base material is soft to the touch and won't scratch your paint, yet it rolls up into a compact package for easy storage. Stormproof is uncoated and untreated; even after months or years of use, it retains the same properties it had when new. Available in gray, black, red, wine, and two-tone combinations with black sides and optional licensed GM logos, prices start at about $334.
