The Original Sand-Free Mat: Constructed with layers of high-density weaving, sand, dirt, and debris easily filter through without coming back up, eliminating a dusty environment. The material keeps sand from sticking to the surface even when it's wet outside while its uv stabilized design keeps its vibrant look from fading. Originally used for desert military helicopters to land on. Lay in front of your Rv or tent to experience a sand-free oasis wherever adventure takes you. All of the Adventure - None Of The Mess: Our unique design utilizes layers of high-density weaving that allows sand, dirt, and debris to fall right through. Avoid trapping sand or dirt inside your car, shoes, and bag - our sand-free mat keeps debris from coming back up.
