The Carefree of Colorado Dura-Mat comes in its own handy storage bag. It opens big, lays flat, and folds up small. It is strong, durable, rugged, and beautiful. Colored vinyl strands and reinforcement fibers are loomed into a woven fabric, then compacted and bonded for exceptional strength and durability. Dirt and water can filter through and it’s hemmed all the way around. It is constructed with reinforced brass grommets for staking the mat into the ground.
