The Elite Supreme Car Cover itself is made up of 3 Durable Layers PLUS a 4th Ultra Soft Fleece Lining to ensure your vehicles surface finish stays in pristine condition. There are two tough yet soft layers of polypropylene, which is an oil based material, with a layer of micro-porous film sandwiched between them to ensure breathability. With the added Fleece Lining there is nothing better to help protect your vehicles finish. Ultimately, this allows for superior rain protection along with the ability for moisture to evaporate through the cover. The material is chemically treated to help prevent UV damage and is also great protection against bird droppings, the effects of acid rain, damage from tree sap, dust, outright dirt and other harmful pollutants. Finally, we weld the seams Ultra-Sonically instead of the use of stitching which ensure the seams wont leak. The suggested retail price is an economical $99.99. The Elite Premium comes with a 3 Year Warranty, Free Storage Bag and FREE Cable Lock which is a $10.00 value!
