Heavy Plush Mats for Mustangs are made with 40 ounces of premium quality polypropylene yarn. The thick 1/2" carpet pile will add to your driving comfort while reducing heat and dampening road noise. These soil and stain resistant mats are easy to maintain. Waterproof construction keeps water away from the original Mustang carpeting. The custom cut, the grommet fastener and the nibbed rubber backing all contribute toward keeping the mats in place.
