It accually is a velcro type carpet... very thick, and it comes with little plastic thingys that you can move around and make "custom" storage in your trunk... like you don't want that 2-liter bottle rolling around in your trunk... it can stop that.walkerwhippet said:I think the gorilla trunk liner is actually that plastic/carpet type material. It's not rubber, but rather a carpet that won't stain or absorb any liquids. I've seen it as a bedliner in pickups that have shells.
