This is the most innovative and unique floor liner there is. You get the look and comfort of carpet, in an ultra-tough 100% polypropylene (essentially plastic) product. That means not only will it protect your Jeeps floor from impact dings and damage, it will stand up to the harshest conditions you can throw at it. The BedRug material is fade and UV resistant. Made of foam similar to that used in life jackets, it doesn't absorb water and will not mold or mildew. Quick and easy installation. 4 pieces: Drivers wheel welll, passengers wheel well, rear cargo floor and tailgate. 3 year warranty. BedRug liners vs. spray-in liners? Quick install and removal - no removal of seats or center console necessary. Heat and noise insulation and removal or grinding of factory paint not necessary.
