Weathertech 421750IM SeatBack Cargo Liner HP Behind Row - 3rd Grey

The WeatherTech 421750IM SeatBack Cargo Liner HP is a custom-fit, one-piece cargo mat engineered to protect your vehicle's cargo area floor and the backs of your rear seats — even when those seats are folded flat. Constructed from the same heavy-duty thermoplastic elastomer (TPE) material used in WeatherTech's best-selling FloorLiner HP line, this grey cargo liner delivers all-weather durability and a premium look that holds up to everyday demands.

Unlike standard cargo mats that leave seat backs exposed, the SeatBack Cargo Liner HP features a patent-pending expandable accordion hinge that allows full, uninterrupted coverage whether your third-row seats are up or completely folded down. No gaps, no exposed carpet, no mess.

Key Features:

• One-piece design covers both the cargo floor and the backs of the last row of seats for complete protection
• Patent-pending accordion hinge maintains coverage when rear seats are folded to the full-down position
• Water retention ribbing system traps spills and moisture to prevent seepage into carpet
• Non-slip nibs on the underside plus hook-and-loop fasteners keep the liner securely anchored on the floor and seat backs
• Trimmable ISOFIX cutout accommodates child car seat attachments without compromising liner placement
• Made from thermoplastic elastomer (TPE) — flexible, weather-resistant, and 100% recyclable
• Contains no latex, PVCs, cadmium, or lead
• Laser-measured for a precise, custom fit — no trimming required for standard installation
• American-made — designed and manufactured in the USA
• Available in Grey to complement your vehicle's interior

Ideal for transporting pets, sports gear, groceries, strollers, plants, or anything else that can create a mess in the cargo area. Because it's a single-piece mat, installation and removal for cleaning takes just minutes with no tools required. Simply wipe down or rinse off to restore it to like-new condition.
