Compatible with i3 Hatchback (2013-2022). The trunk pet mat is made from high-quality material to protect your trunk from drips and spray water, moisture, scratches, dirt, and dog hair. It also provides bumper protection for your car. Two adjustable straps with buckles attach to the rear-seat headrests for quick installation and removal, keeping the seat secure even if your pet moves during the drive. Multi-functional design: acts as a trunk protection mat and a camping mat. It covers the entire rear cargo area to support easy, worry-free travel and family outings. Use scenarios: - Daily pet transport: protects the trunk interior while keeping your pet comfortable during trips. - Camping or outdoor trips: doubles as a camping mat in addition to trunk protection. - Wet or dirty gear: contains water and dirt, making cleanup easier and the cargo area safer.
