A super-warm and eco-friendly backcountry bed.

Ever rigged your bed on little skis and pulled it behind you into the backcountry so you didn't have to use a crappy sleeping bag? That's admirably dedicated, and a whole lot crazy, but check this out: The North Face Aleutian 0-Degree Synthetic Sleeping Bag unzips completely flat, so you can have the warmth of an 15-degree EN-rated bag when things are freezing, and the coziness of a comforter if the night's a little bit warmer than that. It's also full of synthetic Heatseeker Eco insulation, which is made of 30% recycled material, and keeps you warm even if it gets wet, which is something down won't do. The Aleutian isn't a super-light backpacking bag, but it still has a draft-defeating collar and roomy mummy design to reduce weight while maximizing warmth, so you'll sleep better in the mountains than you ever did in your own bed.

  • Synthetic, 30% recycled Heatseeker Eco insulation
  • EN-rated comfort to 18deg
  • Relaxed mummy design
  • Short side zipper
  • Wrap-around footbox zipper
  • Shaped hood and draft collar

Awesome bag for the money!

  • Familiarity: I've used it several times

The Aleutian 0 degree bag is definitely a winner in my book. I've taken it out on several camping trips and it has kept me and the family toasty and warm in temperatures 20 degrees and above. I got four of these for the family for a little more than the price of 1 down sleeping bag in this temperature range. Of course, there are definitely some trade-offs. I will first discuss why I chose this bag over others. First and foremost is the temperature range. My second reason for choosing this bag is it's trapezoidal shape. Mummy bags are just too constricting and a square bag would just be too bulky, and the extra volume would mean it wouldn't be as warm. This bag is the perfect mix to keep me both warm and comfortable. I really like the fact that I can comfortably sleep on my side, curl up, and move about pretty freely, unlike a mummy bag. Of course, that's not to say everyone is going to have this kind of movement as I'm only 5'-3-1/2" tall. Now to the downsides of this bag. It is quite bulky so if you plan to take it out, I'd advise getting a good compression sack. I bought some 30L(largest size) SEATOSUMMIT eVent waterproof compression sacks(awesome sacks by the way) and they fit fine in it. With these compression sacks, I can compress the bags down to about a 10-12" x 9" cylinder. This makes a big big difference from a portability standpoint. Of course, compressing it does not change the weight of the bag which is the other downside to this bag. It's definitely not one you want to take to the back country unless you're going on horseback, but for those 1-2 mile camping expeditions, I wouldn't hesitate one bit. Of course, that's just me. Others on the other hand, may feel differently about lugging around this extra weight and bulk.

As to what temps one should be using this bag for, I would not recommend it for anything less than the EN comfort rating of 18 degrees. If you do, your nights may not be as comfortable as you'd like it to be. Up to 20 degrees, this bag has kept me toasty warm(a bit hot at times). I've been wanting to test this bag in temperatures closer to the EN lower limits, but unfortunately in NC, unless you're in the mountains, the lowest you're going to see are going to be the upper single digits and low teens. To test this bag, I wired up four DS18B20 temperature sensors to my Arduino Uno board, wrote an Arduino sketch to send these readings to Processing via the serial port, and from there, I wrote a program in processing to take these readings and plot them on a graph. My setup had 1 probe to the outside of my North face Talus 4 tent(also purchased from Backcountry), 1 probe on the inside, 1 probe in the bag near my core and 1 probe in the bag at the foot of the bag(inserted via zipper opening). Attached is a graph of how it performed in the low teens. It started at 14.9 degrees and dropped to a low of 11.3. As you can see by the graph of the "foot" probe(pink graph), it dropped to a frigid low of 23 degrees at the foot of the bag. So yes, this did make for a very uncomfortable night for me. For this night, I wore the same as all other nights I've spent in this bag---boxer and a thin t-shirt with no socks or anything else. Freezing I was NOT, as is evident by my core body probe, but very uncomfortable I was because my feet were cold. No matter what I did, I couldn't keep them warm. Of course, adding some wool socks and what not would have helped, but that was not the point. This was sort of an extreme test to test the performance of the bag. When it comes to temps in the 20 degrees and above range, my feet have never even felt the slightest inkling of cold. It's been toasty all the way. I've also run this rig on temperatures near the upper EN rating of 18 degrees and it has performed flawlessly in this range. In 21 degree temps, the foot temps ranged from the low 60's to the upper 70's. All in all, this bag is an absolute winner in my book! For the price($103 when purchased), you simply can't go wrong!

Awesome bag for the money!

Great bag for the price

  • Familiarity: I've used it several times

I bought this Sleeping bag for car camping and its been great. Its heavy and bulky so not ideal for backpacking. But for the price, you cant beat it. Very warm and roomy. It also has a lot of great features found in higher end bags. I would recommend it to anyone on a budget.
