Technalon® covers, made with Kimberly-Clark's Evolution® 4-layer non-woven polypropylene fabric, provide maximum protection in all weather conditions. Often imitated, but never equaled, U.S. made Evolution fabric covers are used by millions of satisfied car enthusiasts around the world. Recent improvements include a stronger outer layer and softer inner layer. The inner layer is constructed with similar processes used for our Dustop™ interior storage covers - gentle protection for fine paint finishes (inner layer is now light gray).
Through extensive testing in Florida K-C has confirmed Evolution has the highest UPF rating of all their non-woven fabrics. This is important because UV rays are what damage both the exterior AND interior of any vehicle. Block the UV rays - protect the vehicle!
