Coverking’s Custom Stormproof Car Cover was developed for those who accept nothing but the best in outdoor-use covers. Stormproof is the culmination of Coverking’s years of tireless research, development, prototyping and testing. This cover is made from top-quality, high-density microfiber—the fiber density is so high that the fabric is inherently water resistant (the only woven fabric that can claim this). Because this fabric is naturally water and UV-rays resistant, no protective coatings are needed, resulting in a cover that won't break down due to chemically-treated fibers that are more susceptible to wear and tear. Incidentally, microfiber fabric is so strong and water resistant that it is now used to make sails for ships because the material exhibits unparalleled durability against the most severe storms.
