WeatherTech 421856IM SeatBack Cargo Liner HP Grey Custom-Fit

The WeatherTech 421856IM SeatBack Cargo Liner HP in Grey delivers comprehensive cargo area protection by covering both the cargo floor and the back of the rear seats — all in one custom-fit, one-piece design. Whether you're hauling pets, sports gear, groceries, or outdoor equipment, this liner keeps your vehicle's interior clean and protected.

Key Features:

• Patent-pending expandable accordion hinge allows the liner to flex when rear seats are folded fully down, maintaining uninterrupted coverage at all times
• Heavy-duty thermoplastic elastomer (TPE) construction — the same material used in WeatherTech's best-selling FloorLiner HP — offering durability, flexibility, and resistance to extreme temperatures
• Water-retention ribbing system traps spills and liquids on the liner surface rather than letting them reach your carpet
• Non-slip nibs and hook-and-loop fasteners on the underside keep the liner securely in place on both the cargo floor and rear seat backs
• Trimmable ISOFIX outline accommodates child car seat attachments without removing the liner
• Custom-fit design laser-measured for a precise, full-coverage fit
• 100% recyclable and free of latex, PVCs, cadmium, and lead
• Made in the USA — proudly American-manufactured

Installation and removal are quick and easy thanks to the single-piece design, making cleanup a breeze. The WeatherTech SeatBack Cargo Liner HP in Grey is the ideal upgrade for anyone who wants more complete cargo area protection than a standard trunk liner provides.
