This bag is awesome. It's light, compressible, big and warm. I have used this bag where it has gotten down to 7 degrees at night and I have always been toasty warm in it. Yes, it does live up to its +15 rating and surpasses it.

The only part of me that got cold was where the bag hit the bottom of the tent and where the sleeping pad did not cover there. So there is that to consider…cold weather camping requires a sleeping pad, but this is true with ANY down bag. I suspect the one negative review here was from someone unfamiliar with this fact.

All in all I am a big guy. 6 foot 1 and about 240 lbs. No part of the bag binds me like some others have. This is probably about the best full featured bag you can buy. Seriously. The only potential negative is the price…but hey you have to pay the most to get the best. Don’t forget this thing comes with 900 fill down. The best down available.

First, (900 down, doubtful, maybe 850... anyway,I have used down bags , love my montbell, got this Helium, and ... its overrated. I dont think its worth the 400 bucks, 200-250 maybe. its slim fitting, I read the above the fella said he is 6'1 weighs 240? wow, that like wearing a coat. the material was nice but I had several hang ups on the zipper, and the zipper its self was tight, and difficult to unzip in the early am. I cant stand to be that confined. 62 inches at the shoulders is slim. I'll be sending mine back

Temperature Rating: 0F, -18C

I'm on my third winter with the Helium. It's a great bag for sub-freezing nights, but much too warm for warmer autumn temps. I use a lighter synthetic bag (Kelty Lightyear 3D) for warmer nights in damp weather.

My coldest night so far in the Helium was 10F (-12C) and wearing only briefs and t-shirt I experienced no cold spots even rolling around a bit. I'm sure I could manage sub-zero temps in the Helium wearing mid-weight thermals or microfleece. The hood can be cinched down to a small breathing portal if you're not claustrophobic. The cinch cords and zips can take a bit of dexterity to undo, but hey...what's the hurry on a cold morning?

Overall, I think the Marmot Helium is a serious moderate cold weather bag true to its temperature rating, light, small in your pack, and worth the premium price.

Summary

This is a lightweight, premium quality sleeping bag. It sets the gold standard for three season backpacking, especially for people in a down-friendly environment like the Rocky Mountains.

Pros

  • Warm
  • Well constructed
  • Top notch materials
  • Compressible

Cons

  • Could be lighter
  • Doesn't have a fancy water resistant shell

I've had this bag for several years, and it is still pretty much the same model. Why? Because it's hard to improve on a near-perfect sleeping bag. The bag is warm down to its 15 degree rating and then some. There are no cold spots and no drafts. That's what you pay for when you shell out three hundred dollars.

Fit is entirely subjective. I'm average height and average build, and the bag is cozy but not small. Entry and exit is standard stuff.

There is no moisture resistance in this bag - Marmot now offers a model with that feature, but I'm pretty sure my Helium will last me several more decades. I don't mind the lack of water resistance. It's a down bag, and backpackers have been able to keep down bags dry for years.

Don't get me wrong - water resistance isn't a gimmick - but it's not a requirement for any sort of outdoor activity. I suppose if someone was on the fence between a synthetic bag and down, it might be a very appealing feature. For most people? Just keep the bag dry.

Packability is excellent. High quality, compressible, warm down and materials that aren't bulky. Once uncompressed, the down puffs up just fine.

This isn't a sleeping bag for someone who likes fancy features. Sorry, it's just not. It just does its job in a way that isn't flashy. The bag is made to last a lifetime, but I usually take a sleeping bag liner because hey, it's a $300 bag.

This sleeping bag has been with me from New Mexico to Washington. I've spent countless warm nights in spring, summer, and fall in it. I suffer from chronic buyer's remorse with most gear purchases, but I've never regretted this one.

I've looked at this bag for sometime, but I really want a hammock quilt. So I haven't bought it.

Summary

Nice materials, very light, looks well made. VERY slim fitting. I am 5'9" weigh 200 lbs, and it's not snug but it definitely is NOT relaxed. The zipper was difficult in the "wee" hours and tended to snag. I like the bag, but IMHO it's not in the same league as a Western Mountaineering bag. Sorry.

Pros

  • Nice fabric
  • Good quality down
  • Marmot name is great, they stand behind all their gear.

Cons

  • Didn't like the zipper.

Warmth, yeah maybe 15. I got a little cold on the bottom, but that happens.

Fit was too snug for my liking, no wiggle room. I know that adds to the warmth. Less air to warm. Exit was difficult. Like I said above, I don't like the zipper.

Moisture, didn't have that as an issue. Packs small. Looks like it's well made. I looked over seams and they all look quality. Had it about 2 months used it twice. Honestly, I felt kinda let down.

Fill: 850 down
Temperature Rating: 15F

This is just a "first impression" of the Helium as I am returning it unused. This is a 2008 model, full zip. I find the "snag free" zipper and draft tube interface unsuitable. The zipper backing is too stiff and the tube too small. Though only a few reviewers have found this a source of cold spots I judged it to be inadequate and didn't want to stuck with an nonreturnable bag.

Other than that it seems to be a well made bag and the breathability of the shell material was superb. IMO, treated waterproof/resistant shells trap body moisture and make for poor down performance. In fact, I have a Sierra Designs 800-fill Trade Wind 15 with the so-called Dri-Zone that is worthless below ~27F. Also my opinion is that "snag free" zippers and waterproof coating are nothing more than marketing strategy or solutions in search of a problem.

I still have my old down California-sewn Trail Wise from 35 years ago and an Eddie Bauer expedition bag from nearly 40 years ago, both are untreated nylon taffeta (also an old Blue Kazoo).

Marmot needs to get back to basics and definitely improve the draft tube design. I live and hike in New Mexico with many side trips to CO, UT and AZ. Spring/Fall high country temps ~15F at night, very low humidity.

Just got back from a trip in the Black River wilderness in central Wisconsin, after sleeping a couple of nights in 2-foot snow drifts. The bag was awesome; any condensation on the bag the morning after was easily wiped up, with no noticeable decrease in loft after 2 consecutive nights in the high teens, wearing a thin fleece base layer and a hat to sleep. I slept with my wet clothes to dry them, and indeed, much of my gear came out dry the following morning.

I found the bag extremely comfortable, highly water resistant, very breathable, and ultra-packable. I've got mine in a small size Sea-to-Summit E-vent compression dry sack, and it comes in at around 11x7, or even smaller, if you'd like to squeeze it that much.

Bottom line: super-plush, 6+" loft, face guard seals perfect, cut is spot on...great balance between efficiency and elbow-room, and, most importantly, keeps you warm PAST its rating (conservative at 15). I have the model with 850 fill and pertex quantum shell fabric.

Great bag, tougher then it looks, but was too warm for me. Have only zipped it up once at 13,000 feet and would wake up sweating in the middle of the night anyway. Never knew I was a warm sleeper until I bought this bag.

Had mine over 4 years now. Just hit 150 nights in it (6 washings). Dang bag looks new. Still as warm as ever when I need it and have managed to keep it dry.

I'm impressed enough to actually recommend it. Big price but well worth it.

As the five star rating indicates, I seldom leave home without this bag. I've used it in temperatures hovering around zero and all the way up to 35 degrees. Invariably I'll throw this one in the car and make a final decision at the trailhead as to which to carry, but the Helium is almost always it.

It compresses down to the size of a cantaloupe using a compression bag, weighs next to nothing at just slightly over two pounds, and generally is warm enough for anything that I encounter.

I previously owned a Western Mountaineering Apache MF (microfiber) 15 degree bag and it did not perform as well as this bag. The Helium bag is warmer, even though it has quite a bit larger cut (roomier), and it weighs less. I can't think of anything bad to say about it. I would have given it five stars if the price was less than $40 or it weighed less than 1 ounce. Stellar bag.

This bag is very light, packs to nothing, features a half-zipper for weight savings, and a great, velcro-free hood system that just makes sense. I've used it several times since I purchased it a few months back. Most recently I spent a 12 degree (F) night and stayed toasty (albeit i doubt it was 12 in the tent) even in just a tshirt, polypro, and liner socks. I am not a warm sleeper and have been very pleased with this bag so far. The DWR is great, and at my size (5'9", 165lbs) the bag is quite roomy for an ultralight bag. Oh, and the draft tube at the zipper is stiffened. The result: I can't make the zipper snag on the draft tube... even when I try!!

First off the most important question.....Does the bag live up to its +15 degree rating? Absolutely not. This bag is comparable in performance to most of your +30 degree bags. The loft isn't nearly as thick as I would like. All this comes as a result of trying to make a cold weather bag out of a two pound package.

The construction and stitching is well done. The shell is not that effective in keeping the down in. However this is my first down bag so this could be the norm with down. It has a draft tube running the length of the zipper to help trap heat in. There are no frills as this is a minimal approach bag. It compresses down to a very small size.

I guess overall I am happy with the bag and for the most part has kept me warm. I just expected to be a little more toasty in a +15 bag put out by Marmot. The company has an excellent reputation so maybe I am one of the few who may be less than thrilled with what they got.

This bag is not unlike a supermodel. She's light and you wouldn't want to kick her out of bed on a cold night. This bag is amazing and it compresses to nothingness!
