I bought this for a family trip to the beach, and it worked great. I have the 8x8 version, and we had a nice sand free area to relax on the beach. The sand just sifts through it, even very fine gulf coast sand. Will take on next scout camp out to see how it works in different setting.
Replaced the Tyvek tarp under my tent with this groundcloth. Sand and dirt don't accumulate on top now and water doesn't pond under the tent. Material seems much sturdier and will protect bottom of tent better. A much better way to go
