Marmot Helium

Rob,

I have the 2008 Helium EQ version, which has a waterproof shell, and is a little heavier.

Great bag….Backpacker Mag has given the whole line of down bags from 40F to 0F their Gold Status….basically it just rates well year after year.

I have used mine down to 5F while layering up my clothing inside of it under a tarp. (I am a cold sleeper)

The cut of the bag is a bit big/wide, which seems to be a common observation.

If you are skinny like me, a narrow cut might be called for.

One advantage of the Marmot Helium is that it might be one of the newer ones with the European temperature rating system, which means it should be true to the temperature rating….see the Marmot website for more on this topic.

I really like the hood, draw string setup…no velcro and very nice feel to the face and cinches up well.

The big "negative" to the bag is that it might not use the lightest material, as it is a more mainstream for the masses sorta bag.

Mine has a full length zipper, the regular Helium for the year that I bought it was 1 lb 13 oz and had a half or 3/4 length zip.

I love mine…think it is a great bag and I would not spend any money on another bag to replace it.

It is my go to cold weather bag.

Good luck and let us know what you decide to do.

P.S. If this matters, I paid $429.00 for mine back a few years back.

I'm with Tony, the EQ version is superb. My buddy also loves his Helium (not an EQ), even though he has the old 1/2 zip version. Both bags are worth the prices, and they seem to be true to their temp ratings. Sure, they're a bit heavy, but oh so warm and packable. By the way, the long versions of Marmot's 850 series have 2" more girth at shoulder, hip, and foot than the regular lengths. I'm 6' even, and I prefer that extra girth, even though the length is a couple inches longer than I need (but it's great to be able to scoot waaay into the bag and create a 2" breathing hole when it gets frigid. If you are 5' 10" or shorter, the regular length will be better. As a point of interest, last fall I picked up a Helium long at REI's 20%-off-Marmot-bags sale. I was hoping it would be 4+ ounces lighter than my EQ, but it wasn't. So I am thinking of selling it for what I paid ($335, incl shipping; it's never been used, just stored in its cotton bag for a few months), if you might be interested. Or anybody else reading this, for that matter (this should be in the gear swap, I guess…). Anyway, I feel that Marmot's 850 series bags all rock. I have a Hydrogen, the Helium, and a mega -40* CWM-EQ–they are all stellar bags, in my opinion.

I've got the first generation 1/2 zip version. The fabric is very nice, it doesn't leak much down, and the hood and foot box are superb. Under 2 lbs for a roomy, legit 15F bag that you can get 20% off several times a year at REI, with their lifetime guarantee…what's not to like?

FWIW, I'm big in the shoulders and a side-sleeper, so I appreciate the roominess.

Haven't tried the Helium, but my Hydrogen had the best hood of any bag I've owned. I'm a cold sleeper and the Hydrogen seemed very underfilled for its temp rating. The current European rating may resolve that problem. I sold the bag and bought a used Nunatak quilt.

I used my Helium for a week in the Beartooths last year around the middle of September. Temps were down as low as 20* at night and I was plenty toasty with no extra layers on. I'd say the temp rating it pretty spot on.

I used mine (old half zip version) a few weeks ago in the low teens in the smoky mtns. As soon as I pull it out of the stuff sack it lofts so quickly and fully that it looks like I pumped it up. I sleep well in this bag because of that girth that others have mentioned. I have had mine for about 4-5 years and it is still my favorite bag I have owned. Marmot should be commended for not shaving weight by shaving interior space. All of the materials are top-notch and it has lasted well.

I will add to the endorsements. I have an older version of the bag with the half zip. The temp rating is accurate, it is quality and fluffs quickly. Good bag for cold weather and mine weighs 28 oz.

+1 on Marmot bags. I have a Helium and an Atom.

Well, it looks like I've been convinced. The difference between the two bags (FF and Marmot) is negligible. The main difference for me looks to be that I can get the Marmot bag from moosejaw for cheaper because they offer free shipping over $200 to Canada and I found a 15% off coupon. So for $330 including shipping I think I'm gold. Someone mentioned about the Marmot bag being a bit heavy. Am I missing something…at 2lbs or less for the regular and 2lbs 5oz for the EQ, that seems pretty light. I'm new to bags so maybe that's considered heavy for a $300+ bag.

I also have the 1st gen. 1/2 zip style. It's excellent, and compares very well with the competition from WM and FF. I think Marmot saves some $$ having their bag shells sewn offshore, but the filling and final finishing of the bag is all done in USA. I don't think you can go wrong for the suggested retail price, and especially for free shipping and your 15% coupon.

I'm in the same situation. I am looking at the Helium and FF Swallow. With my REI 20% discount and $25 dividend check I could get the Helium for about $270 vs $360 for the Swallow.

What's this dividend check I keep hearing about?

If you are a member of REI's co-op, you get 10% back on all full price purchases. The co-op is a one time fee of $20. If you shop at REI regularly, then it's well worth it.

All your purchases for the year are added up, and sometime in March-April, you get basically an REI credit in the mail. If you want, you can even wait until June, and you can "cash out" your REI check for regular money.

I had the Helium EQ, but I sold it because it didn't breath well. I recommend Western Mountaineering bags — and if you need a water resistant bag I recommended their microfiber series. They breath well and are also remarkably water resistant. And if low weight is a priority, WM's ultralight series is phenomenal. Feathered Friends makes excellent sleeping bags as well.

Rob, I'm the one that mentioned the weight thing. What I meant was that when sleeping during a 35*F night, my 2# 6 oz. Helium EQ is overkill, and unnecessary weight. That's where the Hydrogen comes in, saving maybe 9 oz. (a quilt can save even more weight). But if you have just one bag, the Helium will cover all the bases, down to perhaps 0*F (with additional clothing layers). If it's a warm night, just unzip it and let the air flow in. The Helium EQ will be a bit warmer than the Helium, with only a 2-3 oz. weight penalty. That's due to the Membrain fabric, which is more wind resistant, and also essentially waterproof (the seams can leak though). I think you'll be quite happy with the Helium, all in all.

Weighs 1# 12 oz, rated at 20 degrees conservatively, top notch quality.

"Weighs 1# 12 oz, rated at 20 degrees conservatively, top notch quality."

But much narrower. At 59" girth my shoulders barely fit in. If you're built like an ectomorph it would be preferable, but I'm mesomorphic, so it's constricting.

"If you're built like an ectomorph it would be preferable, but I'm mesomorphic, so it's constricting."

I've seen lots of mesomorphs in WM mummy bags. Mesomorphs come in all sizes, from a 110' woman I know who found an Apache quite roomy to a 210 pounder who would barely fit into a Megalite. I guess you're somewhere in the middle. And, yup, you guessed it; I'm an ectomorph. In any case, I just thought it would be good for OP to have an other option to consider. I hope he knows what ecto and meso morphs are. ;)

I am reviving this thread because I am helping a friend buy a sleeping bag and I hadn't been thinking Marmot until I stumbled upon this discussion.

I am looking at the specs for ultralite and the helium and the helium is looking very good.

WM ultralite Price = $380
Size Rating Loft Inside Girth Fill Wt. Total Wt.
6'0" 20° F 5" 59"/51"(knees)/38" 16 oz 1 lb 13 oz

Marmot Helium Price = $370
Size Rating Loft Inside Girth Fill Wt. Total Wt.
6'0" 15° F ? 62"/58"(hip)/40" 19 oz 2 lb 2 oz

Perhaps a better comparison is with the WM Alpinlite
Price = $425
Size Rating Loft Inside Girth Fill Wt. Total Wt.
6'0" 20° F 5" 64"/55"(knees)/39" 19 oz 1 lb 15 oz

The ultralite and alpinelite have a down collar and I think the helium doesn't.

So the helium is 3 oz heavier than the alpinelite and does not have a draft collar. But you can get it on sale somewhere just about any time of the year, not so with WM. I think you can get a helium for around $280-300 without much trouble. So is a WM bag really worth ~100$ more?

I have a summerlite and I love it but if I was making this decision I would strongly consider the Helium.

Any thoughts?

The Helium does not have a draft collar but does utilize a down "face muff" that effectively seals the hood opening. I like it…

Is the WM worth the extra 100? Not sure… the quality of my Helium and Lithium that I have appears to be the same as my WM Antelope and Versalite. The footbox on the WM is a bit tighter, as is the leg area. I find that the Marmots are easier to use whe wearing puffy jackets (esp. down) inside the bag as they are bit roomier.

Moontrail.com has the Helium regular in stock for $369, BUT you also get 60 "bonus" points with which you can choose about $100 in "free" gear.

When I started this thread, I was trying to figure out between an FF bag and the helium bag. I ended up getting the Feathered Friends Swallow bag this past weekend and I couldn't be happier. The bag is fantastic! It weighs in at 1lbs15oz. The material is great, the stitching and quality is superb. I'm super glad I went with this bag. Don't get me wrong, I might be saying the same thing if I had bought the Marmot Helium bag, but I'm not looking back in the slightest. Some people might not care, but I think what made me get the FF bag, was the fact I could pick my color. I bought the orange and it looks sharp. That's my two cents.

Hi Adam,

Jeff K over in gear swap is selling a brand new WM ultralite for $300 shipped.

Hi Jack,

Thanks for the referral. It is almost, but not quite sold pending funds however with a couple people as backups.

Are you enjoying your WM UltraLite you got from me?
