WeatherTech 421845 Polestar 3 Behind 2nd Row Cargo Liner - Grey

The WeatherTech 421845 is a custom-fit cargo liner designed to protect the rear cargo area of the 2025–2026 Polestar 3. Engineered to sit behind the second-row seating, this trunk liner provides complete floor coverage against spills, mud, dirt, pet hair, and everyday wear and tear.

WeatherTech cargo liners are computer-aided design (CAD) modeled using laser measurements of the actual vehicle interior, ensuring a precise, vehicle-specific fit with no trimming required. A raised perimeter lip contains messes and prevents liquids from reaching the vehicle's carpet.
