Technalon covers made with Kimberly-Clark’s Evolution fabric that provide an excellent protection value in all weather conditions. With the highest UPF rating to provide maximum protection against damaging UV rays thus protecting your paint and interior. The 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. The 4-layer barrier protects against bird droppings, tree sap and industrial pollutants and the 4-layer thickness absorbs impacts to help protect the finish from nicks, dings, dents and scratches. The soft-to-paint inner layer is made from bi-component technology blends of polyethylene for softness and polypropylene for strength to assure gentle protection for paint finishes. Two middle layers of melt-blown fibers act as a filtration barrier against most airborne pollutants. This cover is breathable allowing any moisture or heat under the cover to easily escape. Moisture is not absorbed by the fabric fibers which allow it to dry quickly and easily. This car cover is backed by a four-year warranty against fabric flaws and workmanship.
