WeatherTech 421504IM SeatBack Cargo Liner HP Grey - Behind 2nd Row Seating

The WeatherTech 421504IM SeatBack Cargo Liner HP in Grey is a custom-fit, one-piece cargo mat engineered to protect both the cargo floor and the backs of your rear seats — whether those seats are up or down. Laser-measured for a precise fit and proudly made in the USA, this all-weather trunk liner goes far beyond standard cargo mats by covering surfaces most liners leave completely exposed.

At the heart of this design is a patent-pending expandable accordion hinge that allows the rear seats to fold into the full-down position while the liner maintains uninterrupted coverage from the cargo floor up through the seat backs. No gaps, no exposed carpet, and no spills or pet hair sticking where they shouldn't.

Key Features:

• One-piece construction covers both the cargo floor and the back of the 2nd row seats in a single mat
• Patent-pending accordion hinge maintains full coverage even with seats folded flat
• Water retention ribbing system traps liquid and prevents it from seeping into carpet
• Non-slip nibs on the underside plus hook-and-loop fasteners keep the liner securely in place on the floor and seat backs
• Trimmable ISOFIX cutout accommodates child car seat anchor attachments without removing the liner
• Constructed from thermoplastic elastomer (TPE) — the same heavy-duty, rubber-like material used in WeatherTech's bestselling FloorLiner HP
• Flexible and durable in extreme temperatures — won't crack, warp, or break down
• 100% recyclable and free of latex, PVCs, cadmium, and lead
• Tool-free installation and removal for quick cleaning
• Manufactured in the USA

Ideal for hauling pets, sports equipment, groceries, strollers, plants, and anything else that can create a mess, the WeatherTech SeatBack Cargo Liner HP in Grey (Part# 421504IM) delivers high-performance, full-coverage protection for the Mazda CX-5 cargo area behind the 2nd row seating position.
