The WeatherTech® FloorLiner™ accurately and completely lines the interior carpet giving "absolute interior protection™"! Digital laser measurements of interior surfaces offer a consistently perfect fit! A patent pending High-Density Tri-Extruded (HDTE) material allows for a rigid core for strength while offering surface friction to the carpet, as well as tactile feel to the surface! Advanced surfacing creates channels that carry fluids and debris to a lower reservoir with further channeling to help minimize fluid movement while driving!
