The Marmot Helium 15 Sleeping Bag will keep you nice and toasty throughout the majority of the year (I’d call this bad boy a 3+ season bag). The Helium 15 is filled with 610 grams of primo, certified 850+ goose down in Marmot’s Santa Rosa, CA facility and is pretty light for a 15 degree sleeping bag, weighing in at 2 pounds 2.6 ounces. The Nautilus hood features six baffles, forming a 3D hood with the same warmth and comfort found on Marmot’s 8000m Jacket. Marmot incorporated a hood muff to keep cold air out and keep the hood draw cord from scratching that pretty face of yours. The Marmot Helium 15 Sleeping bag boasts many of the features Marmot sleeping bags are known for: an overstuffed, insulated draft tube, zipper guards, both a stuff and storage sack and their classic trapezoidal foot box, which offers tons of room for even Shaq-sized feet. If you’re a cold sleeper, you’ll appreciate the extra warmth this bag offers while out on Spring/Fall trips, and, if you’re a warm sleeper, you’ll find this bag can get you through some quick, early Winter trips. This Marmot down sleeping bag is a favorite for backpackers and mountaineers alike. Get one. Now.

Awesome bag! Super light, plenty warm, and perfect amount of room.I was looking for a bag that would be ideal for week long backpacking treks in the Rockies. So it had to be light weight, compressible/packable, and able to keep me warm if temps drop a bit below freezing. This bag is definitely a WINNER for all of that and more. I'm 6'2" 200 lbs so I got the Long, and it is super comfy! I don't like being too "mummified" and the little extra shoulder room in this bag is awesome. I tested it in my backyard (MSR Hubba Hubba, Exped Downmat) with temps in mid 20's and was plenty cozy. Never had to zip it all the way up camping at 10,000 - 12,000 last July. It packs nicely in the 10L Sea to Summit eVent Compression Dry Sack. Perfect!

Very lightwwight, durably materials. comfortable.Very pleased with this sleeping bag. It feels a little wider than your average sleeping bag of this type which I (even as a slim person) appreciate. The additional room inside is filled with the bag's loft anyways so I see no downside to this especially given the weight.,,,,My particular bag weighs in at 2 pounds 1.9 ounces or 962 grams (without the stuffsack) so 0.7 ounces less than marmot says it should :D. ,,,,My one criticism is the neck baffle arrangement. Does not fully seal you into the bag, but this does not concern me. Anytime I use this bag I will always have a scarf with me so just use this as well thus saving a bit of weight. ,,,,I have found the temperature rating to be accurate.

my go to shoulder season bagI've owned several Marmot bags and have been happy with all of them, including the Helium. They use high end down which keeps weight low and loft high. This bag (like most of their others) has a nice cut, never feel cramped in it. Marmot also does a good job of reporting an accurate rating- this one is no exception,,,,I use this bag mostly for shoulder season use (spring/fall) when I know the temps are likely to dip below freezing. I've had this bag below 20 degrees and was quite comfy simply by adding a little clothing.,,,,Bought my wife one (woman's model), she love's it too! :)

Great Lightweight BagMarmot makes top quality bags and this is no exception. I've had the Helium for a few yrs and the only thing that I'm not ecstatic about is that it doesn't have a true draft collar. If it did have a real draft collar, like my older Marmot Pinnacle, I'd be so ecstatic that it's ludicrous and give 5 stars. I prefer a real collar so that I don't have to close the bag up around my face to keep my body heat in. For me, the temp rating is a bit optimistic and it's more of a 30F bag. At 6' and 165 lbs I got the long- it's a bit big for me, but a medium isn't really long enough.

Amazing bag, worth the moneyI love my sleeping bag! It's warm (I've taken it to 15 degrees and been fine), light, durable, and super comfortable. I'll never go back to synthetic. The quality of the construction and materials is top notch. It also packs down tiny! It's not as fully featured as some other bags I've owned - no little hidden pockets or excessive cuffs or velcro or pillow compartments, but I don't mind. I'd buy it again.,,,,Sizing note: I'm 6'2" and the Long is really roomy in the foot area. If i did it again I'd try to squeeze into a regular.

My go-to winter bagI got this sleeping bag for a trips up through the Rocky Mtns, This thing has helped my weather some very cooled nights. Teamed up with sleeping bag liner, the light weight down help keep me toast in the -0 night of Gunnison Wilderness. I also used it to sleep soundly in a snowcave, while my friends shivered out a cold night. ,,,,Its pack down incredible small as well, just little bit big than a Nalgene bottle. ,,,,I am very happy, I saved up and spent the little bit extra to get this great quality sleeping bag.

a great lightweight backpacking bagI like to keep my backpack on the lighter side. As such, I chose this sleeping bag primarily for its high warmth to weight ratio. It kept me comfortable in the High Sierras in the summer when the temperatures in my tent dipped into the twenties farenheit at night. Hence, I believe the bag to be appropriately rated. However, even sleeping on top of the bag keeps me too warm if the temperatures donât dip to at least the low forties farenheit, so I wouldnât recommend it for camping under warmer conditions.

Good value for your moneyThis has been my sleeping bag for the last two months or so and so far I have been really pleased with it. I have used in environments where its cold but not freezing and it has been very comfortable and nice. I have not tried it where it is remotely moist but as long as its dry around you this bag will do its job. I would say it is relatively easy to pack; not too bulky at all. I especially like that it keeps the region around my head and neck warm and no cold air gets in. I recommend it.
