The WeatherTech Cargo Liners in black (401237SK) are custom-fit floor mats designed to protect the cargo area of a vehicle from dirt, spills, and other damage. They are made from a high-density tri-extruded material that is both flexible and durable, and features a raised lip around the perimeter to contain any messes. The liners have a non-slip surface to keep items in place, and are easy to clean with just soap and water. They are specifically designed to fit the contours of the cargo area in various makes and models of vehicles, providing a perfect fit and maximum coverage.
