This is a pretty cool tent and I jumped on one when SAC had them last spring. But I ended up returning it for 2 reasons:
1) It isn't free standing like the Hubba and Hubba HP, despite their similar profiles. This one doesn't have the Y-frame feature, which means you lose the advantage of being able to pick it up and move it.
2) The roof of the tent is mesh, which means you don't really get the cold weather advantages of a double layer.
Still a nice tent, but not differentiated enough from my Contrail. I guess I was looking for a Hubba HP with lighter materials.
