I tried the bivvy sack on a mild spring night in a high desert location (New Mexico). It did not gather moisture, my main advance concern. I was inside a tent in an arid location. Neither the inside nor the tent ground cloth had no condensation in the morning. The inside of the bivvy sack has a nice soft fiber lining and I left it open, but my legs inside the bottom. I found it to be noisy as I moved. I'm a light sleeper, maybe this wouldn't bother others. It was also very long for my height, 5'3". Lots of extra room.
