Great bag! I am 6"1' and I fit perfectly in this bag, there is no wasted space, but it is still comfortable.

I used this bag on a -6 degree night here in Colorado on top of a Big Agnes Dual Core pad, and I was plenty warm all night, and I was open air, straight on the snow. I slept in wool long johns and socks, with a wool balaclava and was toasty warm all night long. I woke up and there was ice caked on the outside of the shell, but I was warm and dry on the inside. It dried after probably a half an hour.

There is some nice loft to the bag, and the flex baffles actually keep the down centered around your core. Awesome bag, definitely recommended.
