Excerpt: Minimum weight, maximum warmth. That’s the Plasma’s guiding philosophy, and testers approve. The 15°F version won our Editors’ Choice Award in 2011 for its standout warmth-to-weight ratio, and this new model extends the award-winning range.

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.

Excerpt: 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.

Excerpt: 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.

Excerpt: 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.

Excerpt: 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...

1 February 2008
Excerpt: 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.

Excerpt: 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.
