Spent several hours laying out in the snow watching videos on my ipod touch - this thing is WARM
I had side zippers of the bag all open about 1/2 way down their full range. It was about 25*F and I was just about too hot. Not a bad problem to have since I could have left part of the bag in the house (it is two bags in one with a heavy-duty Goretex shell).
My second bag (the Fiancee's) arrived and was NEW - the QC tags that are sewn in were still in place - these just "fall" off when you brush them wrong so I know this thing is really... REALLY... new.
The only problem I have is I'm gonna have to return the Patrol bag since he shipped it in X-LONG when the rest of the kit is regular length.
BTW I'm 5'8 and the regular bag is just great - I'd say it would be fine to 5'10, 5'11 but I like a lil extra space for water etc. in the foot box (which is over-stuffed / double thick btw).
Really happy with this bag =)
