Engineered for the world's harshest environments.
- MemBrain 2L waterproof fabric helps shelter the down insulation from external condensation, snow, and water
- MemBrain 2L fabric is also highly breathable so evaporating sweat won't condense inside the bag and cause the down insulation to clump
- Premium 800+-fill goose down packs down well, rebounds nicely after repeated compression, and features a high warmth-to-weight ratio for ultra-cold nights
- Nautilus 6-Baffle Hood and down-filled collar seal you up against the cold that kills quickly, without a face full of drawcords
- Reinforced Thermo-Pane footbox gives you more goose down so you come home with all your toes
- Oversized, down-filled draft tube along the zipper ensures no cold air gets in
- Hidden draft tube pocket means you don’t have to unzip your bag and surrender your bubble of warmth to find your watch
- Numerous stretch tricot baffles keep the CWM EQ’s shape and insulation in place for years of expeditions on every continent
- Baffles on chest and feet sections run vertically so that rolling around won't shift the down
- Stuff and storage sack are included

Inquiry: would backcountry ship the Marmot CWM EQ Sleeping Bag: -40 Degree Down to Australia? Thanks.
unfortunately BC cannot ship Marmot to Australia due to our vendor restrictions. sorry about that
I'm wondering what size compression sack...
I'm wondering what size compression sack would I need for this bag?
This is an exceptionally big bag with a big stuff sack. The dimensions of the factory sack are 9.5x19" (approx 1375 cubic inches), and the best rule is to start there with a compression sack size that's equal to or greater than what the factory provides. I'll go ahead and use the Sea to Summit Event Dry Sack for reference (item# STS0002). The Large at 9x20" will work with some effort in stuffing, but I would go ahead and size up to the XL at 10.5x23"- you won't loose any ability to max out the bag's ultimate compression, but stuffing it and rolling over the top of any waterproof sack to make the proper closure will be infinitely easier. I've spent too many years wishfully thinking by trying to cram too many pieces of soft gear into too small a sack to think any differently...I used to spit and swear a lot. Just so you know though- compressing down is cool to do and nice (especially with such a bulky piece of gear), but it does eventually beat the crap out of the down and its loft- Something to consider with $700 worth of sleeping bag in the mix. Hope this helps you out.

Chillin on the glacier
This sleeping bag has kept me warm and alive in the coldest and most dire of situations. From the glacier to a bivy elk hunting to my friends yard after a raging party.
I am 6 ft 1 in tall and wondering...
I am 6 ft 1 in tall and wondering which length I should go with as I am not able to try the bag before buying. Are the Marmot sleeping bag lengths usually spot on, or are they known to be big, so I may fit in a regular size?
Go for the long. It might be a little heavier and slightly more $ - but way more comfortable.
Yeah, the long for sure. Aside from just comfort and the extra room to stuff clothing into the foot box, when you sleep (especially on your back) and your feet relax, you're taller than 6'-1" because of plantarflexion.
Peak Lenin in Winter
It's a not a sleeping bag - it's a house!
I was climbing in the Pamirs (Peak Lenin) in winter 2010 and took the CWM everywhere with me. It performed really well in temperatures between -20-31 Farenheit higher up on the mountain. In -10, though, it was just way too warm, uncomfortably warm. I got the 'regular' length and it was nice and roomy for me (5'7).
I would feel comfortable taking it to the higher evevations of the Himalayas.
Hi!! Does anyone know if this bag (or any...
Hi!! Does anyone know if this bag (or any other high quality one) is treated for allergies? Thanks!
Marmot has the best down in terms of being hypo-allergenic. They clean there down thoroughly. Hardly anyone is allergic to down itself but people with allergies to it are just allergic to the dust that is on it. Here is a link that may answer more of your questions on down allergies: http://marmot.com/sites/marmot.com/files/Tech%20Manual_10_FINAL.pdf.
Pages 25 and 26 will bring you to their sleeping bags and down quality.
But having said that if you think you might be allergic to down then go with something like the North Face Dark Star -40 sleeping bag.
This thing works everywhere!
This is the perfect cold weather bag. When paired with the Exped downmat 9 you are ready to take on the coldest weather on earth.
1. Super warm
2. im 6'1 and there is enough room for me to dry damp clothes at the bottom of the bag (i got the long)
3. foot box is comfortable and warm
4. WATERPROOF shell is amazing. I don't have to be constantly concerned about keeping the down dry - i know it's safe. Condensation inside the tent while in the north east is no longer an issue. I get all the comfort and warmth and weight savings of down with out the risks.
5. windproof shell is really nice on mt. washington, NH and in rocky mountain bivy nights
6. hood is comfortable and warm
7. fabric is pretty downproof
1. draw cord system for the draft collar is a pain to use
2. its expensive, but from backcountry and marmot it is a once in a lifetime investment (i bought mine with a 20% sale/coupon)
1. the bag dries out quickly
2. in really cold weather I like to pre warm the bag with hot water bottles (nalgenes)
3. zipper is pretty standard - snags a bit, but no more than most
I've used this bag in New Hampshire's White Mountains for week long trips on Mt. Washington and throughout the winters in Colorado's high country.
Is this warmer than the north face...
Is this warmer than the north face inferno?
The only objective way to answer this is to give you the facts. The Marmot CWM uses 44 oz of 800 fill down while the North Face Inferno uses 47 oz of 600 fill down. So the Inferno wins the 'more fill by weight' contest. I can't find the shoulder measurement for the Marmot bag, but the North Face bag is a little bigger in the hips and the foot box so there is a little bit more volume to keep warm in the Inferno which will also contribute to the warmth of the bag.
800 fill european or american? because north face uses european ratting and marmot the american one.
A note of clarification:
1. 800 fill down is warmer than 600 fill down, so a lighter weight of 800 fill will be warmer than a slightly heavier weight of 600 fill.
2. having extra space in the sleeping bag means there is more volume for you to heat. Heating dead space in the bag wastes precious body heat. Avoiding convective heat loss is one of the primary reasons people use liner bags.
I don't know. The only person who could really know would be someone who has used both - and even that would not be conclusive. Every bag is unique, and every person is unique.
I had a very hard time finding comparable facts for the two bags, different manufacturers publish different specifications (like I could not find the foot box circumference for the Marmot (M), and I could only find the LONG specs for the North Face (NF). However, the NF seems to have 47oz of 800 FP down compared to 48oz of 800 FP down in the M (both longs). The 44oz mentioned earlier for the M was the regular. Someone mentioned the difference between European and American FP calculations. The European one uses a heaver compression piston, so their measurement is more conservative (750 FP European ~ 850 FP American). However, I could not determine if NF used one standard and M used the other. I DO know that Marmot has all their bags (except this one) tested in Europe for CN rating.
My bottom line review - based on my experience - is this: every North Face bag I've had (I've had 2-3), has seemed cold at or near it's rated temperature. I've tried a Marmot bag and I have a Mountain Hardwear bag. Both worked well (for me) at or even just below its rated temperature. I would buy a Marmot bag over a North Face bag any day of the week, all things being equal. However, to put it into better real-world perspective, I would buy the North Face Inferno over the Marmot if I could save at least $100. I do not need a -40F, I need a good -20F.
Hope this helps!
LOL - three years later and I have the Marmot -40. Unbelievable bag, though I have not used it yet. Think of this though... you can lie on top of it and the loft does not go down. And I'm not a light man... Expect an update after I try it out in northern NH!
