No matter how much you try, you cannot try to cover the Sandless Beach Mat with sand. The mat has been made out of two layers of patented woven polyurethane that can instantly filter sand whenever it falls on its surface. It’s kind of a one-way filter which will prevent sand from re-emerging through the bottom of the mat. Apart from this, the mat will also eliminate dirt, dust as well as water from the surface and ensures a clean surface free from sand whenever you’re camping or watching some concert at the beach. It also resists abrasion from outdoor furniture or pets with the bound edges remaining flat. The mat will not absorb moisture. All in all, an ideal mat you should always carry whenever you’re out for camping or just a day out at the beach.
