Excellent 3-Season Bag

The Marmot Hydrogen is a great bag to own. For a 800+ fill bag, it's reasonably priced and very warm and lightweight. I've had a lot of success using this bag below 30 degrees by combining it with a thermolite sleeping bag liner and/or down clothing as well. If you pack accordingly, I think you can safely trust this bag close to 10 degrees. I've personally slept with this bag in Joshua Tree's deserts in January and also in Northern Michigan Spring through late Fall with great comfort. Treat it with care and you can expect nearly a lifetime of service from a bag of this quality.

My only gripe is that I'm not a fan of the stuff sack it came issued with. It is difficult to pack and does not have any compression straps to condense the bag to a smaller volume. I've since gone on to replace it with a waterproof compression sack and I really recommend this as an accessory to the bag. You'll cut volume, the weight is negligible, and you'll add insurance to your bag by waterproofing it. You'll come to appreciate this if you ever get caught up in a storm or fall into water with your pack (as I have) or discover that your kayak's bulkheads weren't nearly as dry as you thought they were. Well worth the investment and has greatly improved my experience with this sleeping bag.

I was looking for a lighter weight summer bag that would still work on the cold nights in the High Sierras. I just came back from a 5 day trip in Yosemite were we were camping around 9000' most nights. Temperatures ranged from 40-60 degrees at night and this bag worked well. If the temperatures dropped below 40 degrees I would have needed to put on long underwear and more layers but that is to be expected but I think I would be pretty cold at 30 degrees. The zipper and bag are fairly sturdy and the lining is very comfortable against the skin.
I'm 5'10, 165lbs and female and the regular bag fit very comfortably. I'm happy with the bag and will keep it.

I love this bag! It is incredibly light and packs down to a very small size. I decided to buy this after seeing it stuffed into its stuff sack in person and I couldn't believe the size of it. I only like to use a 55L backpack during the summer to keep me from getting sweaty and this sleeping bag fits perfect. If you don't mind the sticker get this bag! I had trouble deciding with this bag over a western mountaineering but I have had great experiences with Marmot and trust the brand.

A good fit for drier conditions.

This is a good 3 season bag: light weight, compact and a snug fit. I have used it down to 16 degrees where a bag liner and a tight tent allowed me to stay sufficiently warm but not comfortable; I tend to sleep warm. At this point, I wish I had purchased the Helium (20 degree) bag for winter use in the Washington Cascades. For 30-degree or warmer weather, I would now opt for a lightweight compact synthetic bag.

And today's magic trick will be....

The Hydrogen is certainly like a magic trick when you're pulling a 30 degree bag out of a football sized stuff sack! For people who enjoy kayak touring, this bag fits great into any hatch. I've also used it on numerous backpacking trips and been very pleased with how light it is and the amount of space it DOESN'T take up. I'm generally a cold sleeper, but the half zipper and snug fit keep me nice and toasty.

I get cold easily, and I've never had a very nice bag, so I've missed out on a lot of camping! First night I used this bag it was 35 out and I was warm and cozy in this bag. It is very light and packs down nicely.

One of the best bags I've ever used (and I have 10+). Small, VERY compressible, warm. Perfect for normal sized people. If you're a bigger guy, it's a little on the small size, but still okay since you're backpacking. If you're car camping, take something from Cabelas.

zolotoi at Backcountry.com on 02/14/2013

I slept in this bag in 5 deg Celsius (about 40f) and with windchill colder. This bag is everything people say it is - fantastic - very warm and comfortable (and feels snug but not tight (I am 5ft 7 inch). Don't hesitate.

jonebee592151685 at Backcountry.com on 02/06/2012

This is a fantastic bag, the 850 fill down keeps you warm, but is very lightweight. I'm 5'9.5'' 165lbs and the reg works out really well. There is enough room to sleep on your side, but it is nice and snug.

Sunn Kim at Backcountry.com on 05/17/2012

Great bag, as light as they come without spending half a grand. True to temperature rating. Packs down small, very small with an aftermarket compression sack. What more could you want, really? Marmot makes great stuff.
