Not very durable, but then it's only 3.5 mil. I got this to use as a footprint under my tent. It worked well for about three outings, which were on regular ground. The tent site on this last trip was hard pack and gravel. Now the tarp has several small holes. I'd used a 5 mil tarp under my previous tent with no issues, even after two seasons on various surfaces. I'm going back to 5 mil.
