Protect the cargo area of your 2025 or 2026 Cadillac OPTIQ with the WeatherTech Cargo Liner, Part Number WET421846. This vehicle-specific liner is computer designed to fit behind the second-row seating, providing comprehensive coverage for the trunk and cargo area. Its raised lip helps contain spills, dirt, grease, and other messes before they reach your vehicle’s carpeting or interior trim, helping reduce wear from everyday use.
The WeatherTech Cargo Liner is manufactured from a proprietary custom-blended thermopolyolefin (TPO) material engineered for durability and flexibility. The wear-resistant construction remains flexible through temperature extremes, making it suitable for year-round use. A textured surface helps keep groceries, luggage, equipment, and other cargo from shifting during transport, while also providing a practical surface for routine loading and unloading.
Designed for convenient ownership, this gray cargo liner installs easily and supports quick cleanup when spills or debris occur. Remove the liner from the cargo area, clean the surface as needed, and reinstall it for continued protection. The WeatherTech Cargo Liner can be paired with a compatible WeatherTech Bumper Protector to help shield the vehicle’s bumper surface from dings and scratches while loading or unloading items or pets. The bumper protector attaches to the cargo liner with durable, rust-resistant stainless snaps. This cargo liner is tailored specifically for the Cadillac OPTIQ and is intended for behind-second-row cargo area applications.
