So warm and light, you'd think you'd died and gone to heaven.
- Lightweight 850-fill goose down insulation offers a superior warmth-to-weight ratio and rebounds well after repeated compressions
- Marmot's goose down comes from mature geese, the down of which has larger filament clusters than a young goose's, and larger clusters mean more pockets of trapped air and therefore more warmth
- Pertex shell is super lightweight, stands up to frequent use, and breathes well to keep the down insulation from clumping
- DWR finish repels frost, dew, and condensation
- Down-filled draft collar and full-length draft tube protect against areas where cold can creep in unexpectedly
- Face Muff allows hood to be cinched without irritating your face
- Large trapezoidal foot box decreases constriction at the bottom of the bag
- Nylon stuff sack and a storage bag included

I'm looking for a winter bag for quick...
I'm looking for a winter bag for quick overnighters in the Wasatch mnts. I'm very concerned about compressed size as I'm trying to assemble a cold weather kit that will fit in my 32 liter BCA Float Airbag pack and allow me to start some dawn patrols by arriving in the evening.
I've purchased the REI Magma and also the Lithium to compare them. I like the size and weight of the REI, it compresses into a 10 liter compression bag whereas the lithium requires a 14 liter. Laying in them in my bedroom, they both seem comfortable for a side sleeper like me. They are basically rated the same on the EN scale. The REI bag is cut much trimmer and has 5 ounces less fill. Both have great reviews on REI and Backcountry sites. When they are sitting on my bed, side by side, the Marmot has significantly more loft, it reminds me of a Western Mountaineering bag based on loft and cut. This makes me wonder if the bags, with such a significant difference in loft and fill weight can really be comparable in terms of warmth. That said, the extra loft and fill on the Marmot makes it take up significantly more room in my limited space backcountry skiing pack. So I find myself torn. The marmot seems the better bag, but the REI bag seems to meet my need for compressibility better, while still being a solid bag. It's important to note that I paid the same price for both bags, which was below the $300 mark. (the lithium was on clearance at local shop's fall clearance). I can use the REI bag and return it if it doesn't work out. However, the lithium is a different story as it only has a 30 day return . So I'm trying to make a decision as to whether the Marmot is a nirvana enough bag to go ahead and deal with the reduction in space in my pack or not.
I've included a picture of both side by side for comparison. The REI bag in yellow, the Marmot in blue.
chad, based on all the specs provided, the marmot should be the warmer bag. that being said, they have very similar en ratings. the rei website states that 60% of the down is on top of the magma, so that may be the mechanism that gives it a similar rating. also, as you stated, the magma is a slimer bag, which allows it to be warmer thana roomier bag.
This is how i see it: the en ratings show that they provide a smiliar ammount of warmth, though the marmot will provide more insulation as per the higher fill weight. the rei bag is more restrictive than the marmot, so you really need to see which is more comfortable to sleep in. i would like the roomier bag as it is still just as warm, but i should sleep more comfortably. i'm willing to sacrifice some pack space for a better night's sleep.
great bag-makes others look anemic
I really like this bag-I havent used it a ton due to I have other bags I use alot as well. BUt, I recently went out and compared it to my friends MH phantom zero degree-Maybe it was just their bag but this has way more loft-way more fill inside as well.
A plus for me is that these bags are finished and filled in SOcal.
The temp rating is accurate-perhaps conservative.
Excellent, toasty bag!
- Familiarity: I've used it several times
I'll keep it brief as most of the highlights of this back have already been pointed out.
This bag is very warm, super lofty, and compresses like a dream! I took it with me just recently on Mt. Baker and Mt. Rainier and it performed well, even when part of it got wet from snow melting around our tent and spilling some soup on it. I am a 5'8'' woman and comfortably shoved several layers of clothes to dry out down around my feet, and I still kept warm, didn't feel confined in the bag, and my layers dried out and were also kept warm.
Even with some nights in single digits, I slept in a lightweight baselayer and was still comfortably warm.
The drawstring on the draft collar and draft tube down the zipper worked brilliantly in sealing my body off from the cold outside.
Overall a great bag, didn't feel confined (I'm a side sleeper that rolls around a bit), and all the compressibility and warmth you could want from a down bag.
Just as comfortable as it can be...
- Familiarity: I've used it several times
I used this bag in all the my six days of Kilimanjaro climbing last January, and spent a comfortable night inside its crater (-20C), with just a fleece liner inside. It grabbed me in my guts. Fantastic piece of gear for cold mountains.
Alexander I can't tell you how much I...
Alexander I can't tell you how much I appreciate all your effort and time! I can purchase this bag with complete confidence thanks to you.
Very grateful and wishing you all the best,
No problem man, I understand having a lot of questions when you're about to drop $500 on a sleeping bag, I'm the exact same way. I'm glad to do it. Enjoy the bag!
Yep, knowledge is power. Trial and error is never a substitute for doing your homework to the best of your abilities. We do it for others and others do it for us. It's a cycle...and it never really ends, no matter what you know already or don't know yet. Enjoy!
Sorry Alexander last question, as you can't...
Sorry Alexander last question, as you can't migrate the down I just need to be clear on the down distribution, you answered earlier that the down was "for the most part 50/50", could you explain, for the most part? I like the bag to move with me when I'm sleeping on my side so having even down distribution is important to me. I apologise for all the questions, I don't want to send this bag back so better to be clear before I purchase it. Super quick responses and very helpful. Cheers!
Not a problem DS, I love nerding out talking about gear and my wife is sick of it hahaha. Ok so I pulled out my bag for you and it's definately a 50/50 split. I'm uploading two pictures for you that might help you see the distribution. The seam in the center is the side seam opposite of the zipper. You can see that the loft is equal on both sides, hence 50/50 and will definately keep you warm when sleeping on your side. Like I said, I'm a side sleeper too and I'm usually too hot in anything above 5 degrees. You should find this helpful in making your decision.
What the hell, I'll throw in too. I don't want to pull out my bags, but the split is roughly 50/50, or as close to it as you're going to get. I'm a side sleeper and have both WM and Marmot bags that go to 0 degrees and below. These, in my opinion, aren't just well made, they're well engineered. When I properly select based on the temperatures, I'm never cold in any of them, and I'm usually in boxers, a t-shirt, and sometimes socks. My thing is that I twist and turn, a lot, but even when I shift the down around, which is impossible to not do, my bags do what they're supposed to do. That's nothing really more than buying a good quality product.
You'll be stoked on this bag, even after you've owned it for years.
Cheers Phil, that's just confirmation.
Hi Alexander I asked previously but it...
Hi Alexander I asked previously but it might have been missed, can you tell me if it has continuous baffles, can the down be shifted top to bottom and vide versa if needed?
Thanks for you responses.
Here is a picture from Marmot's website illustrating the baffle construction
is the only difference between the this...
is the only difference between the this bag and the membrain lithium bag the membrain itself? the reason I ask is on the description of the membrain lithium it states extra down in the footbox. thanks.
No, they're the same. Both bags have 28 oz. of down in the entire bag, same baffle construction The only difference is the membrane.They're awesome bags. Hope this helps.
Thanks Alexander thats really helpful,...
Thanks Alexander thats really helpful, just one more question, have you had any problems with the neck collar and it's ability to create a seal? I've read that it can be a problem, otherwise I think this will be the bag I will go with.
Thanks very much for your help.
Not at all, you might be referring to Outdoorgearlab's review? I've used this bag as low as -20 degrees (with a liner and baselayers) and it hasn't been a problem. There's a drawstring on the neck collar and the hood as well that you can cinch down really tightly if you need to. I haven't found it to be a problem at all, however if you do, I assume that's why both you and I shop at Backcountry, because of the unlimited guarantee. I think BC is the only game in town that still does it.
One more thing, I usually find myself waking up in the middle of the night on single digit nights having to completely open the neck collar and hood because I'm sweating so much. I hope this helps.
Can you tell me if the Marmot Lithium has...
Can you tell me if the Marmot Lithium has a 50/50 down distribution top to bottom, I'm a side sleeper? Does it have continuous baffles? I read further down this page where the Membrane shell was compared to the Western Mountaineering MF shell, can you explain the Membrane shell construction, is it a laminate?
I own the non membrane version of the Lithium and for the most part is a 50/50 split as far as I can see. I'm also a side sleeper and have no problems in this bag going as far as the temp rating recommends. As far the Membrane is concerned it is a two layer laminate which gives it higher water resistance. I hope this helps. I'm a huge fan of this bag.
Warm and small.
Packs down pretty small in a 16L compression sack, can't argue with the weight at just over 3lbs for the long. I've used it a handful of times in the Eastern Sierra Nevada in temps from around 10 to 30 degrees F - as it gets hotter you'll want to keep the zipper open, but it can be unpredictable in the spring so its nice to have the extra warmth when the wind picks up and the sun goes down. Bag is great for late fall, winter, and early spring Sierra Nevada - outside that i'd go with the 30 to save even more weight and space.
Warmest 0 degree bag!
I was looking for a down bag that was warm and be light enough to pack. I currently have a Marmot Hydrogen that is used during early archery elk hunts with great success, but needed something for late season. The Lithium is part of the Ultralight Series family from Marmot so I thought it would be a natural. So far, I've not been disappointed! It is certainly one of the warmest bags I've ever used.
One well-designed part of this bag is the hood pull cord, which remains comfortable even fully cinched. Most other sleeping bags place the cord on the outside edge of the hood (it's easier and cheaper), but this is uncomfortable when the hood is fully cinched because the tight cord smashes up against your face. Marmot does a great job addressing this problem.
If you are looking for the warmest 0 degree bag with a comfortable hood, stuffed with 28 ounces of top quality 850+ fill down, light weight and stuff-able, this is THE bag! I highly recommend it!
Lithium 0 and Helium 15
Both in long versions in stock stuff sacks of different sizes. I've been able to compress them both down to full compression in a Granite Gear 16L compression sack. Size wise I feel like you can pretty much compress them equally, weight wise I measured the long versions at 51.20oz and 38.15oz respectively. I feel the Lithium will fit my quiver of bags better than the Helium so that will be my choice. A Lithium for winter and a Hydrogen for late spring, summer, and fall in the Sierra.
Marmot Sleeping Bags: Simply The BEST
- Gender: Male
- Familiarity: I've put it through the wringer
If you know anything about why or how Marmot came into existence you know how legit they are when it comes to backpacking.
Their Sleeping Bags (and Tents) in my opinion are SIMPLY THE BEST in the Outdoor Industry hands down.
Watch the vids on how to take care of it and you'll get years & years of warmth in the backcountry...
...quality over quantity Mmaann!

does anyone know the foot cicumference of this bag in the regular and long?
It is 40 inches for the regular and 42 inches for the long.
Hope that helps!
Marmot lithium 0 degree
used this bag at 10000 feet early this spring -- i don't know what the temp dropped to at 0500 am but when i got up with the sun it was so cold i had difficult time manipulting the lighter to start my stove -- my fingers ached and went numb -- there was ice in the creek -- anyway i was very warm in the bag and i am a cold sleeper --- alot of loft -- at 3 pounds its not bad to pack in -- the bag is well constructed -- no down coming out of it -- no rips -- the tent i used had a solid ceiling and it rained on me in the morning as the sun came up -- the lithium shed it well -- and the outer layer dried out quickly laying out in the sun -- i have 3 marmots and the flap that covers the zipper will sometimees snag so pull the zipper slowly and with care -- but the zipper flap covers well with no cold spots ---- one way to test a bag for cold spots is to open it up and hold it against a bright ceiling light -- one should see the down evenly dispersed throughout the baffles -- i have 3 marmots and all of them pass this test -- i have looked at high end bags that failed this simple test and declined on the purchase cause of clumping down in the baffles - if you are a warm sleeper you might check out the marmot plazma 15 degree bag for this kind of weather - it weighs in a 2 pounds -- anyway Marmot is all i trust and the only bags i will carry -- suggest you do your research and purchase one
does anyone know what's the difference...
does anyone know what's the difference between marmot lithium and marmot lithium membrane sleeping bag?
The outer shell. The regular lithium uses 20-denier Pertex Microlight nylon, and the Membrain version uses (depending on the model year) either Marmot Membrain waterproof fabric, or Pertex Shield waterproof fabric. Basically, one's water resistant, the other is water proof.
2 years and still going strong
I've had this bag now for about two years and it's still my go to bag in anything under 30 degrees. I've used this in temps around 0 degrees and it's pretty true to its rating. I've also used it in temps as low as -20 but wanted to play it safe and used a fleece liner. The bag compresses down to about the size of a volleyball which is amazing, cause for such a lofty bag, it's super packable. Once out of the compression sack it lofts up in a about 5 minutes to full size. Overall great bag, i'm so happy with it.
I'm exactly 6 ft, so would the regular be...
I'm exactly 6 ft, so would the regular be "snug and warm" or cramped and awful. Inversely, would the large be too large (i.e. drafty)?
At 5'11" I'm not far behind you, and ALL my bags are longs. The extra room is mostly at the bottom on my bags, which is helpful, since I put my boots in at the bottom to dry.
The shoulder circumference for this bag in Long is only 2 more inches, so you're not gaining a significant amount of space around you.
Just got back from Nepal and India. This bag was great- it was used everywhere, from filthy hotel rooms to high mountain passes and it performed wonderfully. In Bhimthang, Nepal, near Mt Manaslu we were snowed in after our guest house was blown down in a blizzard (no lie). 1st night I awoke as the roof was being torn off, and the bag was already covered with 4 inches of snow. I was warm and cozy, but evacuated with the group due to the obvious structural instability of our guesthouse. The bag's shell got wet, the down never did. Great bag, and it compresses small (just don't store it like that!)
