Coconut Coir: This light brown door mat is made of 100% pure coconut coir, which is one of the strongest natural fibers in the world. The material easily captures moisture, dirt, and other particles. Due to the way our coir mats are cut, sizing may show slight variations. In addition, light shedding may naturally occur. Attractive Design: The eco-friendly material has a heavy-duty .60 thick pile, and is made so there are no patches where you can see through the mat. With coconut coir doormats, some shedding is inevitable, but through our professional shearing procedure we ve reduced it to a minimum.
