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

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.
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!
does this marmot lithium bag qualify for 20 % discount?
NO, I found out after I had ordered it! The fine print excludes marmot products.
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.

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!
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 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.
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 "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!)
Helium in compression bag and lithium without.
Anyone got the pack size of this bag?
Marmot states 7.5 inches by 15 inches.
Took this baby out for the first winter camp yesterday, temps dropped to somewhere around -2F(-18C) and I was warm and cozy all night. Got ALOT of condensation in the tent so the bag got pretty wet but nothing soaked thru so I'm very happy with that. Stuff sack is pretty small so getting it down takes some work, zipper gets stuck sometimes but not too bad. I'm 192cm, sleeping with my liners in the long bag wasn't a problem.
Marmot's own Curly Cervone and Brian Rashap show you how to care for your Marmot sleeping bag.
SUPER WARM,SUPER LIGHT,GREAT
I'm interested in the Lithium, but cannot decide on the sizing. I'm 6'2" 185. Would I fit in a regular?
I'm 6'3" and I'd go with a long. Mummy's are cut to reduce extra space wherever possible, including the length. You can probably squeeze into the regular, but it probably won't be all that comfortable.
Ok, hard decision. I'm also eyeing the Western Mountaineering Antelope MF which is rated to 5°F/-15°C and has the advantage of being made of a weather resistant MicroLite XP shell. If you had the choice between the Marmot Lithium and the Western Mountaineering Antelope MF which one would you choose? Goal is to be light weight and warm in the coastal mountains (where also humidity is fairly high, so often lots of condensation in the tent). As regarding these two criteria there might be not much difference, how about the durability of the material?
Marmot also makes this bag with a MemBrain shell...similar to the weather resistant MicroLite XP. Either way, you've got two great bags. I'd say they're both pretty accurate on their temperature ratings as brands (at least in my experience) and the materials/durability are both great, but the Western Mountaineering might be slightly better. Also, while Marmot bags are filled and finished in California, Western Mountaineering bags are made entirely in the US. I'm not sure where the Marmot bags are sewn.
How is the lithium doing regarding feather loss? It the shell material pretty good in letting not much through?
I'm looking for a warm and lightweight sleeping bag for winter camping in the coastal mountains at the west coast of Canada. This years temperatures went down to -30°C, though everyone told me that usually it doesn't get as cold and I should be generally fine with a -10°C bag. So I would like to get a bag with which I'm comfy at least down to -15°C. However, I get cold very easily, and I'm seriously afraid of freezing. So what sleeping bag to get? The
lithium seems to be a good choice. Anyone used it at -15 to -20°C? Any other recommendation?
The temp rating on this bag is accurate so you should be good down to -17C
I've used the bag in around 0 degree nights with just a wool baselayer and was very warm. If you're really that concerned just spend the bucks and get a wamer one.
