Calif. Car Cover has covers made out of Supremeweave, Plushweave, Dustop, Superweave, Stormweave, Noah, Softweave, and Multiweave II. You match the intended use of your cover to the appropriate material and order accordingly. This offers you several options, although for regular indoor garage use only, I use the less expensive Softweave, which comes in red, black, or grey and is 100% cotton. Pete the ex glass guy
