The Bedrug Mat protects the floor of your truck bed and contours to the floor of your bed to give you a nice flat surface for your cargo. The mat is slip resistant so items will not easily slide around in your truck bed while accelerating or stopping and is resistant to most common automotive chemicals and pet stains. Made of UV resistant polypropylene fabric and is easily installed using the supplied industrial hook and loopstrips. The mat will arrive rolled up and should be laid flat and allow it to relax to help with the installation.This mat works great without or without a tonneau cover.
