WeatherTech 421733IMSK SeatBack Cargo Liner HP with Bumper Protector

The WeatherTech 421733IMSK SeatBack Cargo Liner HP with Bumper Protector delivers comprehensive cargo area protection for 7/8-passenger Expedition and Navigator models, covering both the cargo floor and the backs of the rear seats in a single custom-fit piece.

Unlike standard cargo mats that only protect the floor, this liner extends coverage up the back of the last row of seats, eliminating exposed carpet and upholstery whether the seats are upright or folded flat. A patent-pending expandable accordion hinge allows the liner to move with the rear seats, maintaining uninterrupted protection in any seat position.

Key Features:

• Laser-measured custom fit — precision-designed for exact coverage with no gaps
• One-piece design — covers the cargo floor and rear seat backs together for complete protection
• Expandable accordion hinge — maintains full coverage even when rear seats are folded flat
• Water retention ribbing system — traps liquids and prevents spills from seeping into carpet
• Non-slip nibs and hook-and-loop fasteners — keep the liner securely in place on both the floor and seat backs
• Trimmable ISOFIX outline — accommodates child car seat attachments without removing the liner
• Includes bumper protector — guards the rear bumper edge against scratches and scuffs during loading and unloading
• Heavy-duty thermoplastic elastomer (TPE) — flexible, durable, and resistant to extreme heat and cold
• Free of latex, PVCs, cadmium, and lead — 100% recyclable material
• Made in the USA — American-manufactured quality

Ideal for hauling pets, sports equipment, groceries, strollers, outdoor gear, or any cargo that can create a mess. Tool-free installation and removal make cleanup quick and easy. The WeatherTech SeatBack Cargo Liner HP with Bumper Protector is the definitive upgrade for full cargo area protection.
