MontBell U.L. Alpine Down Hugger #5 Sleeping Bag: 40 Degree Down - 2007 BCS

The sizing of this bag fits my 5'8" 145# body well. There is plenty of room to move around without feeling confined. The temperature rating isn't exactly accurate. When using this bag on the fourth night of a two week outing, the temps dropped to 50. I was using a silk liner and had to cinch the bag completely to get warm. I eventually had to add a thermal shirt when the temperature dropped to 48. I looked at the bag in the morning and held it up to the sunlight. I could see gaps in the down where there was no insulation at all. My bag may have been slighted on some of it's down.

This bag was great for a mid-summer camp at 10,000 feet in Colorado. It packs super small so it's a little deceiving as to how warm it is, but it was absolutely perfect. The temp probably got down to 50 at night and I couldn't have been more comfortable. I can't wait to use it again soon. One other note, it looks more purple in person than the blue color on the website.

just got this. haven't had a chance to use it on the trail yet, but i've slept in my room and it's great. pros: stuffs very small (slightly larger than a nalgene), very comfortable (elastic system works), and while i'm not sure yet, i feel like i could use it down to its rating. cons: its purple, it looks blue on the website, but its one of those purpleish blues.
