Fender Cover f/A-4 Ball Style - Black Fender covers should be as tough as the fenders they protect. That's the criteria we used in developing the Elite Fender Cover series. Polyform uses a premium grade yarn that is resistant to sunlight and abrasion. They are womven 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 three year warranty
