Super warm bag for a good price and not a lot of weight!I absolutely love this bag for it's warmth and loft. Sleeping on snow and ice in -20 degree temps I was nice and toasty. It's also super roomy so you can move around in your sleep without feeling like you're trapped in a coffin. I haven't noticed any cold spots, so the insulation is great all around. The little pocket near your head is great to stash a headlamp too!

I used this bag on Denali! I slept like a baby!This bag is expedition ready! The little holder for your iPod keeps it warm throughout the night. There's a thicker layer at the bottom to stop any drift snow from ruining your night's sleep.,,I wouldn't go into the mountains in Winter without the bag, into the Andes without this bag, into Alaska without this bag and into the Himalayas without this bag!
