Used this bivy for first time on 27 mile overnight trip. Very easy to set up and light weight. Fit a Nemo pad & Marmot sleeping bag. Weather was light rain and mosquitoes were terrible. The bivy has options for bug net vs. rainproof cover for the head. It was snug (I'm 5'7" & 190) in the bivy and fairly stuffy w/ the waterproof cover zipped down during rain. I slept most of the night with the bug screen zipped all the way and waterproof cover 3/4 way zipped for some air. Outside of bivy was covered w/ moisture from the rain and there was minimal moisture on my bag which was impressive. The new "breathable" fabric seems to really improve the condensation issue. My only issue is there are only two spots for stakes to help keep the bivy taut. It would be nice if there was a stake loop at all 4 corners. That's my only complaint. Well made piece of gear.
