Hex 3 user/owner here. No nest, just the tarp. Just had mine out two weeks ago. Given what's its designed for and its inherent limitations, I like it. It's well made, easy to pitch on a level site, and roomy for its weight. Condensation is manageable. If you don't use trekking poles you'll have to carry a pole of course. My main gripe is that I can't pitch it lower, like all the way to the ground. In cold/windy weather I don't like that gap at the bottom.

It's probably going to be my snow shelter this weekend too.

What do you specifically want to know?
