I'm in the initial few weeks of a four month review of the Q Core.

It's not comfortable for me unless I let some air out. At 3.5 inches it's a pretty cush ride. It is heavier than my favorite, the NeoAir, but also rated to 15F so will be going with me into alpine conditions in July.

Oh, and the hammock? Worth having for any below treeline adventure. Best sleep you can get. I still wake up multiple times at night, even on my Exped, or the Q Core, or the NeoAir - all awesomely cush - but I can sleep a solid 10 hours through without disruption in the hammock.

NeoAir is the lightest and most compact of the mattresses. The Q Core I have is 27 oz for a 72" model. The Exped (mine is a DownMat 9) is my winter pad and quite hefty at 2 lbs 4 oz - that's heavier than my 3 season tent.
