I have an Atko in addition to at least 10 other backpacking tents from Black Diamond, Walrus, MSR, etc. I also do most of my backpacking in Colorado and the desert southwest where humidity is not a problem. I like the design and quality of Hilleberg tents for the most part, but condensation is DEFINITELY a problem. I invariably wake up with a wet sleeping bag in the Atko, even with all vents wide open. I've never had a condensation problem with any of my other tents.

Condensation is pretty much a way of life over here, and the Hillebergs are by far the best at dealing with it! After having used many tents that drip on me in the early hours, I now wouldn't change my Hilleberg!!
