The WeatherTech 13+ BMW X1 Rear FloorLiner in Black is a custom fit floor liner designed to provide maximum protection for the interior of your vehicle. The patented tri-extruded composition allows for a rigid core for strength while offering surface friction to the carpet, as well as tactile feel to the surface. The FloorLiner is laser measured to protect the entire floor from front to back, including the back seat area. The FloorLiner is made from a proprietary custom blended TPO (thermopolyolefin) that is not only wear resistant, but also remains flexible under extreme temperatures. The FloorLiner is designed to keep spills, debris, mud and dirt away from your vehicle's carpets.
