Construction & Design

The WeatherTech Cargo Liner is crafted from premium TPO, a thermoplastic material known for its exceptional durability and flexibility. This material maintains its integrity across a wide temperature range, resisting cracking in cold weather and softening in heat, which ensures long-lasting performance regardless of climate conditions. The liner’s textured surface not only provides a non-slip platform for cargo but also adds a rugged aesthetic that complements the Jeep Grand Cherokee L’s interior styling.
