"A practical protector for the load compartment that covers the floor and side walls of the load compartment plus the rear of the rear seats. Made from durable, dirt-resistant vinyl.
Gives very effective and fully covering protection of the load compartment when carrying dirty loads. The protection has an integrated dirt cover that can be folded down over the bumper. It prevents clothing from becoming dirty and protects the bumper when loading and unloading.
The back section of the cover can be separated by a Zip, so that the rear seat backs can be folded independently of each other. The cover is also equipped with various pockets on the side walls, including a net pocket with Zip for storing various items.
The load compartment cover is easy to use and is simple to secure and remove. It is secured using elastic straps around the head restraints and with press-studs, which are secured to the floor and side panels."
