Marmot Hydrogen Sleeping Bag: 30 Degree Down
Marmot for Life
This is the second Marmot bag I've owned and wasn't sure if it could get any better...well it did! I previously owned a Never Winter bag and it suited me very well for the past 3 years, I simply had found a buyer for my old bag and wanted to upgrade and decided on the Hydrogen. A stuff sack can't contain this bag, it just wants to stay lofted all the time! I got the long version even though I am only 5'10" and 170 pounds, simply because I squirm a bit, but the bag as a regular surely would have been roomy enough, so stick with what the manufacturer says, if you're under 6ft, go with regular. Like the company's logo states...Marmot: for life...I will never buy a down bag from anyone else. Period.
Good overall
I hiked a little over 3000 miles this year using this sleeping bag. I spent many nights in this bag when the temp dropped to the teens. I'm not going to say I was toasty every time, but I wasn't hypothermic either. You can't beat this bags weight to warmth ratio. I could stuff it to fit into a climbing helmet, and fluff it back to life day in and day out. When it was warm out I didn't always have enough ball room... so use it as a blanket. I would highly recommend this bag. Just know its limits and your own.
Highly recommend this bag
I have tried a number of ultra-light sleeping bags, and this is one of the best. From my perspective it meets all of the Manufacturers claims. I would recommend it.
Marmot Hydrogen 30 Degree Down
I bought this sleeping bag because I needed the lightest bag I could find with the most warmth to pack in my 25 liter motorcycle backpack. It's tiny when packed, leaving room for lots of other necessities. We've camped in -2 to -4 degree (centigrade) weather so far this year and I can say that this bag did the business every time. While a little more expensive, it's terrific bag for the money if you're after the lightest, warmest bag around.
Yes
Disclaimer: I'm totally Marmot biased due to their continued focus on the highest quality, design, and great customer service. I own or have owned Marmot, Sierra Designs, Mountain Hardwear, The North Face, etc...If you want the best warmth to weight ratio bag out there for most 3 season conditions, this is it. Yes, it is a little tight, but not too bad. My only 2 complaints (prefer longer zipper and/or foot ventilation) would take away from the weight trade off. Mine measured in at 1.65 lbs with stuff sack. (it's the long model). Great bag!
