Often imitated, but never equaled, U.S.-made Evolution® fabric car covers are used by millions of car enthusiasts around the world. Evolution® has the highest UPF rating to provide maximum protection against damaging UV rays. Protecting your paint and interior helps maintain the vehicle's value. Polypropylene fibers are bonded into a durable 4-layer non-woven finish that includes a soft bi-component inner layer of polyethylene and polypropylene fibers.
All-Weather Car Cover Protection Using Film Barrier Technology - 380 Series fabric is Kimberly-Clark’s newest film barrier fabric, offering great performance at a competitive price. The three-layer construction uses inner and outer layers of spunbond, sandwiching a middle layer protective film barrier. The film barrier has microscopic holes, smaller than droplets of water (and most dust particles) to stop moisture but still allow any moisture vapor or heat to easily escape from under the cover.
A Mid-Price Car Cover leader in Quality & Performance - Kimberly-Clark developed Block-It® 200 Series fabric to be a mid-price leader in quality and performance. It uses 3-layer polypropylene construction for moisture and dust resistance, and the fibers are treated for extra UV resistance. If you are looking for an inexpensive cover for indoor storage and limited outdoor use, this U.S. made fabric offers good, basic protection and is an excellent value.
