Protect the cargo area of your 2025-2026 Chevrolet Equinox or GMC Terrain with the WeatherTech 421856IMSK SeatBack Cargo Liner HP. Designed for behind the second-row seating, this custom-fit gray cargo liner covers the cargo floor and the backs of the rear seats, helping shield your vehicle from dirt, mud, grass, pet hair, spills, groceries, sports equipment and everyday debris. The integrated bumper protector helps defend the loading area from scratches and messes when placing items in or removing them from the vehicle.
Made from the same heavy-duty, rubber-like thermoplastic elastomer used in WeatherTech FloorLiner HP products, this one-piece mat combines flexibility with durable, high-performance protection. Its patent-pending expandable accordion hinge allows the rear seats to move into the full-down position while maintaining continuous coverage. A water-retention ribbing system helps contain moisture, while non-slip nibs and hook fasteners on the underside help keep the liner securely positioned on both the cargo floor and seat backs.
The WeatherTech SeatBack Cargo Liner HP installs and removes easily for convenient cleaning. Its trimmable outline accommodates ISOFIX child-seat attachment points without requiring removal of the cargo mat. Built to withstand extreme weather conditions, the liner will not break down easily and is 100% recyclable. It contains no latex, PVC, cadmium or lead, and its American-made construction delivers reliable protection for active families, pet owners and anyone who regularly carries messy or bulky cargo.
