ELITE FENDER COVERS. Fender covers should be as tough as the fenders they protect. That's the criteria used in developing the Elite Fender Cover series. Polyform uses a premium grade yarn that is resistant to sunlight and abrasion. They are woven by a special knitting machine that produces a seamless tube so you don't have to worry about seams splitting and allows for a heavier yarn content. The result is a fender cover that is built to last for many years and not just a season. Features: hand-crafted with heavy duty polyester fabric for durability, Washable, Custom fit for a tailored look, Drawstring closures instead of elastic - which can become brittle and break, Quick and easy installation, Limited 3 year warranty
