Quick, easy setup, even in high winds. Blowing snow can't get you when you're inside setting up. Truly light, bomber, and warm. Definitely too warm for summer unless you like the greenhouse effect. I also use the optional door fly, and it's perfect for cooking in the mountains. Couple of problems, though. I let a friend set it up once--she missed one of the floor grommets and over the course of the night, it ripped a hole in the floor. After 4 years of seriously hard mountaineering use, it's starting to come apart at the seams a little. Still weatherproof, but I'm thinking about replacement.
