My GF uses that tent when backpacking . She loves the weight of it . I’ve never slept in it but have set it up and it seems well made .
I don’t think it’s been in extreme weather though
The big con that turned me off the zpacks tents is that the material is really noisy in windy conditions. Most thru hikers wear ear plugs at night but I'm not wearing ear plugs at night in bear country. The noise could also spook game.
