The WeatherTech FloorLiner DigitalFit 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 HighDensity TriExtruded (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 d riving. Once fluids become trapped in the reservoir, away from shoes and clothing, they are easily removed from the WeatherTech FloorLiner DigitalFit over the door sill. No muss-no fuss.
