Construction & Design

The WeatherTech Cargo Liner is crafted from a proprietary thermopolyolefin (TPO) material, which is specially formulated to combine toughness with flexibility. This ensures the liner withstands heavy use, resists cracking or warping, and adapts to temperature fluctuations without losing shape or durability. The raised lip design is engineered to trap liquids and debris, preventing them from reaching your vehicle’s carpet and causing stains or damage. The textured surface not only adds grip to keep cargo stable but also enhances the liner’s overall durability.

Each liner is precision-cut using computer-aided design (CAD) technology to match the exact contours of the Jeep Wrangler Unlimited JK’s rear cargo area, ensuring a seamless fit and maximum coverage.

Simply place the liner into the rear cargo area, aligning it with the factory contours. The liner’s flexible material and custom fit keep it securely in place during normal use.
