Best benefit I see is the weight for the size of it, (6 pounds is pretty amazing) which might not be such a big deal for a car camper. Might interest those coming on airplanes. It isn't really standing height except near the center, with the sides being 43". Would be a neat evening hanging out cave perhaps.
So for shade, it would be mainly sitting shade, and could be a bit of a baking experience unless there was a way to roll up the bottom and get some more airflow.
I think with good guying out and sturdy poles, it could shed the wind as well as a cabin tent. People camping in snowy places, get snowstorms and those can be windy.
Kurtz: Are my methods unsound? Willard: I don't see any method at all, sir.
