CGEARSAND-FREE LIFE Unisex's SandLite Sand-Free Beach Blanket

It is great mat, huge can easily fit family of 5. We used it on all types of survives, sand, grass, stones. On the sand, the sand does come up a little bit but will fall through back, so you don’t have Lift the whole family to shake off the sand. It is very expensive may but I think it is worth it if you use it regular.
