I like this bag a lot, but agree that it may not cut it for extended cold camping.

Love this bag! Just got back from a camping trip where it rained non stop. Some rain actually came in through the roof vent on my MSR MoRoom tent. But an awesome fact was discovered and that was that the bag is somewhat water repellent right from the store. I woke up in the morning(totally toasty) and there were beads of water on the top from where the water came in from the torrential rain. But whatever bag you get make sure you have great insulation between you and the ground. My REI pad only has a 3.2 R-value but i went to walmart and bought a $5 foam mat that worked perfectly. The temps only got down to around 34 degrees at night but it felt colder with the constant rain. Its not the lightest bag and probably not the bag your looking for on a long trek, but for the money, you cant go wrong. PS. the draft collar makes a huge difference at keeping your warmth in..a feature in any bag to look for..

One of the best ones Marmot makes in my opinion. I'm a pretty warm sleeper and this is perfect for nights in the single digits. If you are pushing 6' go for the long, it will be much more comfortable.

I found this bag to be a lot warmer than i had thought. Used it for a few chilly nights in northern GA on the southern end of the AT. Kept me nice and warm, almost too warm actually, granted I was in GA. Anyway, my only complaint about the bag is the size, it does not pack down that well but I have been happy with it keeping its feathers and you cant go wrong with real down fill!

For the price you can't beat it. Kept me warm in low single digits, actually got to hot and didn't zip it all the way up.

This bag is a great choice for those who want/need a bag that supplies warmth at a better price than the mountaineering bag prices. This bag is true to rating, I spent a few nights in well below freezing temps and I was toasty. All in all a great choice.

I recently used this bag in the Pharaoh Lake Wilderness Area in the Adirondack Park. The temp dropped below 0 degrees and I was still toasty. The bags features are great. It has a great draft tube, two different drawstrings so you can tighten to your liking in the dark without pulling the wrong cord (there's one for the head and one for the draft tube). This bag also has a ton of loft. I spent two nights out in this below 0 weather and was quite comfortable. It did ice up a bit because of condensation but it didn't affect the warmth at all. If its a problem for you just wash it in a DWR coating and that will take care of the problem. This bag is compact, light, extremely warm and can be used for a solid three season bag (winter, spring and fall). Way to go Marmot

I have the long version. I'm 5'11" 225lbs and this bag is perfect for me, it could definitely handle someone a bit taller than me but not much wider than than I am, lol. It is very warm at sub freezing temps...I have not nor do I intend to test it all the way down to zero degrees but I'm confident it would be at least comfortable at that temperature. I the draft collar is a nice touch and the hood cinches up nice and tight for those extra-cold nights.

I bought this bag right before late winter backpacking trip in north eastern WI. I lows for that weekend were to be between 15 & 20 degrees. This bag performed great in these temps I was almost too hot in the bag. Everyone else froze and I was toasty warm. All in all I am very pleased with the bag. I would definitely recommend it to everyone that is thinking of doing any type of cold weather camping.

This bag has down dandruff, and it's not nearly as warm as I was expecting. I've used it to 10 degrees and needed more layering than I should to keep warm. I do sleep a bit warm, too. Not very water resistant, the bag was wet through the fabric from condensation. And it's heavy by a pound compared to others in its category. It's roomy, and the collar is a nice addition for the price. I also appreciated the water bottle compartment in the toe box. On value alone it gets a 4. But more importantly, it doesn't compare to other bags for the intended use. If I was on a shoestring budget it would be a tough call because when you're cold, wet and shivering the $100 or so you saved isn't what's running through your mind. For another $140 you can have a Feathered Friends bag (Lark) that sleeps warmer, is much more water resistant, and weighs over a pound less.

I picked this sleeping bag up in anticipation of a winter ascent of Wheeler Peak in New Mexico. Upon initial inspection it seemed to be a nice bag made with good materials. It was a little on the heavy side and did not compress as much as I would have liked it to but the price was right. The first night we camped at 9,400 ft and the temperature dropped to 15 degrees and I was toasty all night. When I woke up the next day I noticed that the bag was damp towards the bottom of the bag but it didn't seem to be an that big of an issue so we kept moving. The second night (which ended up being our last night) we camped at 12,000 ft and a huge snowstorm moved through dropping the temperature to 0 degrees. Once again I was toasty until about 3:00 am and I starting getting chilled especially below my waist. I shoved my down jacket in my sleeping bag and wrapped it around my waist to get me through the night. The next morning when I woke up around 6:30 the inside of my sleeping bag was completely frozen with ice. Somehow in the middle of the night moisture had crept into the down and froze solid. The snow storm ended up forcing us down before we made the summit but I don't know if I could have made it through another night with this bag. Needless to say that I lost my faith in this bag and I'm going to be returning this bag today.
