These are excellent mats. Woven from a tough polypropylene rope with UV inhibitors, they are resistant to rotting, ripping and fraying due to exposure to the elements. They are also reversible (same on both sides), and the coarse rope helps to remove mud or snow from your footwear.
The mats are easy to clean with a hose; the dirt simply washes right through them. They are both colorfast and mildew proof. For use on non-slip surfaces.
