Product Reviews
Rated 5 out of 5 by from The Beast [This review was collected as part of a promotion.] This sleeping back is ridiculous. When it lofts up it is huge and super comfortable. Then you can pack it down into a stuff sack. The first time I thought - that isn't going in there. But it can be done. This bag is warm. That's an understatement. This bag is subarctic.

Rated 4 out of 5 by from 3.5 stars to be exact but it's very warm and comfy [This review was collected as part of a promotion.] I'm a cold sleeper living just a bit north of Pacific Northwest and this is my first sleeping bag. The winter here can be down to 15F and humid. So my top priority were warm and waterproof / resistant then as backpackable as possible. Also the one I bought was the old model, which does not come with a stuff sack with strap. Pros Very warm Very comfy Con It's very bulky and the stuff sack is so small that it is IMPOSSIBLE TO STUFF IT ALL IN. LITERALLY IMPOSSIBLE. I had to buy a 30 liter Compression sack to hold it and even after fully Compressed, I can only pack it down to roughly 26-27 liter. So the figures published on the product page was not attainable. I don't know if the new model with the new stuff sack will be able to improve on its packability. I still like it and will test it when the winter comes, but bought a 2nd bag that's warm and comfy but pack down to 16~ liter. My point is beware of this if your top priority is backpackable. Take the published figures with some reservation and this is a warm bag. The zipper snag right out of the box, and it's far from being smooth. Again, I don't know if the new model improved on this.

Rated 5 out of 5 by from Super sleeping bag! [This review was collected as part of a promotion.] Just make sure you know what you’re buying-this is an extreme below zero cold weather sleeping bag. Very happy with bag for above 10k below zero temps.

Rated 5 out of 5 by from This should be your first and last bag Great bag!!! I wish I could go back in time and buy this bag years ago. In the past I have always bought bags that were cheaper and not able to handle the cold, as a result I have had some very uncomfortable nights and several bags. FINALLY I bought a bag that can works! Do yourself a favor buy the best bag you can first and save loads of money and you will get many good nights of sleep for years to come.

Rated 4 out of 5 by from The right tool for job! [This review was collected as part of a promotion.] I recently used this bag in the Arctic on a Muskox hunt. The wind chill was -51 the first day of our trip. The bag preformed flawlessly. The only thing that could be improved is the zipper. It needs to be a bit larger to function better. Other that that it performed flawlessly.

Rated 5 out of 5 by from Worked as a charm [This review was collected as part of a promotion.] This sleeping bag is amazing - camped out at the MN/Canadian border over the frozen lake for a week and it kept me warm and comfy.
