Here's what other sites are saying:

From Campmor:
"Remarkably light and compact, the Marmot Helium fifteen degree down sleeping bag delivers impressive insulation. Use it as a three-plus season bag to substantially reduce your load while backpacking and mountaineering. 850+ Fill goose down. Stretch tricot baffles. Nautilus hood. Hood draw cord. Velcro-free face muff. Passive collar helps prevent heat loss around the neck and head. Full length zipper for easy in/out. Down filled draft tube. Zipper guard keeps the fabric from getting caught in the zipper. Classic trapezoidal footbox for more room. Ground level side seams. Stuff sack and storage sack included."

From Backcountry.com:
"The Marmot Helium Sleeping Bag packs smaller than a loaf of bread and takes you down to 15F weighing an astonishing 2lb. Versatile and ultralight, this 850-fill down sleeping bag ranks among the lightest on the market in its class. Perfect for spring and fall adventures (or even mild winter conditions), the Helium packs away efficiently in smaller packs. Just because it's featherlight doesn't mean it skimps on features. A full draft collar seals in precious heat while a mummy shape lets you hunker down when need be. For spring peak bagging and high desert trips, the Helium is your bag of choice."

From Moosejaw:

"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."

"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."

"I was so excited about my Marmot Helium, the weight, the fit, and the size of it. It worked well for me on the first few trips out and nearly for the first year. I began to notice that some feathers were coming out, although I couldn't find a hole."

"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."

"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."

"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."

"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."

"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."

"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."
