Construction & Design:

The WeatherTech Cargo Liner is manufactured from a proprietary thermopolyolefin (TPO) blend that balances toughness with flexibility. This material choice ensures the liner resists wear from heavy cargo and remains pliable in extreme temperatures, preventing brittleness in cold weather or deformation in heat. The liner’s raised edges are molded to contain liquids and debris, while the textured surface enhances cargo stability. Each liner is precision-cut using computer-aided design (CAD) to match the exact contours of the Rivian R1S flat cargo bed, providing seamless coverage without gaps or overlaps.

Installation & Fitment:

Installation is straightforward and requires no cutting, drilling, or special tools. The liner simply lays flat into the cargo area behind the second-row seating of your Rivian R1S. Its custom fit ensures it stays securely in place during use without shifting or bunching. This product is specifically designed for the flat cargo bed configuration of the Rivian R1S Adventure and Explore trims from 2022 to 2024, and it fits all 2021–2026 models with this cargo layout.

• One WeatherTech Cargo Liner for the flat cargo bed area
