Sand Free Beach Mat: Nobody likes sand all over their beach mat when they're about to sun bathe! A sandless beach mat, however, will solve this common problem.  Dual layer mesh technology, it allows sand to fall straight through leaving the mat free from sand! Awesome! So be prepared with one of these sand free beach mats.  How A Sandless Beach Mat Actually Works The real genius behind one of these special beach mats, which were originally developed for military use, is that they actually consist of two separate dual-weave layers.  The top layer (and indeed the bottom layer) allows sand particles, dust and dirt to pass through to the other side, whilst the bottom layer helps prevent sand coming up from underneath.  So any sand that happens to accumulate on the mat will quickly disappear through to the other side in an instant, creating a sand-free environment in which to relax, and if there does happen to be any large lumps of sand, you can simply rub the sand into the mat with your hand and watch it disappear.
