Not Quite 3 person
I used this tent over Memorial Day weekend down in Moab, Utah. Tent was fairly easy to set up. The poles are great, but the hook and loop closure tabs on the inside of the tent are not the most convenient way to attach the tent to the poles. The vestibule/rainfly just folds back over the tent, you don't have to worry about zipping it off or anything, which was great when it cold down at about 2 a.m. as I was able to jump out fold it back over and close it up.
The tent itself is not big enough for 3 adults, we got two in but really didn't have much room for gear, the rainfly/vestibule isn't really big enough to store 2 peoples packs/gear. I liked the tent, but would prefer something a bit bigger to be able to comfortably have two people and gear.
