It doesn’t matter how careful you are when you place your beach towel or blanket down by the sea; all it takes is one iota of a breeze to get pesky sand particles everywhere. Forget it after that – there’s no getting the sand off then. Unless you have the CGear Sandlite Sand-Free Beach Mat ($50-$100), specially designed for this very problem. The blanket is made of two layers – the top one is mesh – and when sand hits the mat, it falls through the mesh and down to the second layer. It’s a one-way game – the sand can’t come back up! The technology was originally designed for the military, so you know it’s been tested. This might be the smartest thing you can buy the family for your next beach day.
