Rated 5 out of 5 by from I zipped 2 together! I bought one of these last year with the left zip... and I love it. I use it in Alaska where everything is super wet or super snowy and the waterproof shell is aaaaamazing. This year i bought another with the right zip. I put em together now and my lady and I are comfier than ever. I’ve got nothing but great things to say about this bag. I’ve heard the zipper gets caught, but I always have a guide finger when zipping it and I’ve never had an issue. I’m 6”2 with some broad shoulders and I fit great in it.

Rated 5 out of 5 by from A great Alpine bag! I'm through my 2nd winter with this bag and have used it in Alaska in in northern Minnesota winters with temps from 20 degrees to -26 below zero. The Pertex Sheild (outside layer) is super durable and waterproof/breathable. The draw cords for the hood work great to keep you warm and allow moisture to exit the bag. I'm 5'-11" and have the Col long. There is plenty of room for extra base layers, gloves, socks and water to stay warm by my toes.

Rated 5 out of 5 by from Love it. This bag is a solid choice for winter. I've slept in snow trenches and snow caves at 11,000 ft in Colorado in this thing. It kept me warm and stayed dry in damp conditions. It's roomy- There's just enough space to move around in and keep your essentials inside to prevent from freezing. It is not a claustrophobic bag. The zipper is a bit funny at times with some snagging but not unworkable. It is a big sleeping bag, and I'd only haul the weight for winter camping. I love this thing.

Rated 5 out of 5 by from Final word in warmth I have used this bag in -38 F and was warm as toast. This is simply the finest extreme cold weather bag currently on the market today. L

Rated 5 out of 5 by from Good warmth to weight ratio I bought this bag for Denali. I wanted a warm bag but something reasonably light and compact. I had previously used a -40 bag and thought with 2 tent mates a -20 would suffice. It was enough warmth and I was able to get my sleeping bag and down jacket into one compression stuff sack. It also is roomy for sleeping with a water bottle, extra clothing, etc.

Rated 4 out of 5 by from Like a cloud I love my col long. This bag is so roomy and comfortable. At night I can fit my down coat and pants, boot liners, water bottle and some extra food to get through the night and not have frozen food in the am. My bivy is a pinch to small at the footbox to have all the stuff I put down there but if I’m in a bivy with this bag it’s either seriously bad weather or past it’s rating. My only serious complaint is the zipper snagging on the draft tube but the fact that you can lift up the tube and feel an ice cold zipper and then push it back down and have no cold spots is fine with me. You know this bag is waterproof because when I dry it I need to dry it inside out to get my full loft back before storage. It keeps water out but also in so just take this into consideration and try to stay as dry as possible inside it. Most people buying a technical bag like this though already know that.

Rated 5 out of 5 by from Warm, well-made, and roomy I bought this in the belief that someday I would be glad I over-invested in a warm bag. That day came last weekend when the temperature fell 15 degrees lower than the forecast. As a primarily fast and light warmer-weather backpacker, I thought long and hard about the extra weight (and size) of a super warm bag. After a fair amount of research, I convinced myself that since I could get this one for about the same weight as many zero-degree bags, I would be happier carrying the extra protection it would provide. I am a cold sleeper who will avoid a zero degree night if I can help it, but sometimes a cold night chooses you rather than the other way around. I addition to keeping my patootie warm, the things I particularly liked about the Col are: --It's roomy and not constricting. I am a side sleeper and can move around and switch sides for my aging hips without getting tangled up. I'm 6'2' and maybe could have gotten away with the regular length, but it is nice to have space for other things that you don't want frozen solid in the morning.  --The head area is well designed and very comfortable. I thought I would be cinching it around my face with an opening to breath through, but it is much nicer than that. I have a curved pillow that fits just right above the neck baffle and it creates a chamber where I can rest my head sideways with the opening as more of a skylight above. --It feels solidly built, durable, and impervious. The pertex works great. The entire interior of my tent can be frozen up with condensation and somehow the bag is dry and crystal-free. It feels like a tank compared to summer ultralights, which I feel like I have to protect. --The adjustments are intuitive and the zipper works. Sounds minor, but in the middle of the night when I want to adjust something, the cinch is where my fuzzy brain thinks it should be. The surprise was the hidden pouch at the end of the zipper baffle. The zipper itself has a protective strip sewn along it. I still manage to get it stuck sometimes, but it is easy to get going again. The only thing I wish was different (and I can't blame the bag for) is that it's big. Bigger than I thought, and so solid that it is hard to squeeze the air out of it to get it into the stuff sack. It takes time and effort to get it stuffed, and it is still big and makes for a big pack. Even storing it uncompressed takes a lot of space--and makes it harder to hide that I have a new toy. The snap on the neck baffle is uncommonly tenacious when it is cold and fingers are stiff, but I can live with all that, if it is the price of being warm at 3:00 am.
