The WeatherTech SeatBack Cargo Liner HP safeguards the base and up the back seats of your vehicle's cargo area, even when the seats are down. The patent-pending, expandable accordion hinge allows back seats to retain protection while in the full-down position. A water-retention system traps water before it can damage your interior. Non-slip nibs and hook fasteners on the underside keep it in place. This cargo liner boasts the same heavy-duty, rubber-like material as the best-selling FloorLiner HP, offering a durable 1-piece mat that defends against spills and messes. The SeatBack Cargo Liner HP defends against the dirt, grass, mud, and debris that come from workout gear, dogs, sports equipment, groceries, or anything else you put in your cargo area. The custom-fit design tailors to your vehicle's year, make, and model, for a truly personalized solution. Mfrs. lifetime limited warranty.Manufacturer model #: WTSBCLHP0.
