Comparing Marmot Hydrogen to Western Mountaineering Summerlite
Awesome Bag

- Familiarity: I've put it through the wringer
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.
Great bag

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.

Would this bag be warm enough for climbing Kilimanjaro? Im 5'10 and get cold very easily.

This is an excellent bag and you can help the temp rating by the layers you sleep in. With that said, if you get cold easily I would go with a 15 degree bag like the Helium.

Been looking at getting this bags for awhile, but I am still a little sceptical about using it in the early spring time. We're planning a trip for early May and this usually the earliest I will go. Do you think it is a good buy for that time of the year?
knanier
Member since
This could be a great bag in May. It could also kill you in May - all depends on where you're going and how the temps will be. I've found my Marmot bags are pretty comfortable down to their ratings. I usually sleep on the colder side, but find among my friends that I'm about average.
Great bag - don't hesitate - treat yourself

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.

Yes, you won't have a ton of room(I'm guessing you're used to that), but you'll be fine.
Phil Maher

Western Mountaineering makes a couple models in a 7'-0" length that you might be happier with. Roughly a $150 more and rated for a lower temps, but great quality, wide cuts and light weight. I fairly recently got a Badger MF and am really happy with it.

I am a big guy, 6 ft. tall 300lbs. How roomy is this bag? I have a Thermarest NeoAir to go with it. So if this is not the way to go, what would you recommend?
Thanks!
Dwayne Vincent
Member since
You will probably want a non "mummy" style, and probably a long also, 300 is a big boy, and you will be pretty tight in this one
knanier
Member since
I would also check out some of the big Agnes bags - they're designed to be wider and roomier. Be cautious though, as some do have non-insulated backs requiring a sleeping pad to be inserted into a sleeve. Your NeoAir may fit, depending on size.

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.
So Sweet!
Ian Pickard
Member since
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.

Hey, I'm looking at a 30 degree, lightweight bag for summer, late spring and early fall in Idaho. I am having a lot of trouble deciding between the Marmot Hydrogen, MontBell U.L. Super Stretch Hugger #3 and the Western Mountaineering MegaLite. Anyone want to give their two cents to help me decide?
knanier
Member since
I've had great experiences with Marmot and Western Mountaineering temp ratings being spot on if not a little better and I'm a fairly cold sleeper, so I'd stick to one of those two. Good luck and don't forget about backcountry.com's unlimited return policy!

YinYang

I am thinking about this one or Western mountaineering Alpinelite. I know their rating temp. are different, but I want to know which brand has better construction quality, best materials... Western mount.hasn´t a pocket inside.
moroni
Member since
In my opinion, Western Mountaineering makes the best sleeping bag on the market. They use only 850 fill power goose down & their materials from the weight reducing Microlite XP to Gore Windstopper are the most state-of-the-art materials you can find. If you're looking for an inside or outside sleeping bag pocket, these bags are not for you, but as an added bonus, they're Made In The USA!
Amazingly Comfortable
Justin
Member since
Kept me warm in 30 degree weather and is very comfortable, even better if you add a pillow to the equation. Some nights I've even preferred sleeping in this bag than in my own bed.

Tom Rottmann
Member since
I have an older model (05) that I used on my 06 AT hike. I cannot say enough on how great it performs. At that time I think it was a 900 fill not an 850. I heard Marmot was changing it to an 850 fill due to the difficulty of obtaining enough 900 fill. More importantly, it was my understanding that the shell of the bag had an upgrade option of being more water resistant then the 05 bags. The only two times the bag posed a problem was when it got wet in the shelter due once to a water bottle breaking in the rack above me and once to a trail dog wanting to get warm on a very rainy night. Is the current shell of the bag the one with the more water resistant option then the older bags? For the longer trails, trust me, every bit of water resistancy will help.
Tim Coats
Member since
The shell's have changed since 2005 (then pertex quantum now lightforce) but I would guess the water resistance of the two fabrics are fairly similar. If you really need water protection you could go to the warmer Helium EQ bag, which uses a laminated Membrain shell.
Super Bag

This will be real quick. I went back and forth about buying this bag thinking about buying something cheaper and I am not saying you can't get a good bag for less, but this bag is so comfortable and light and packs down so small, that if your on the fence and have the dough, don't be. It is a solid purchase, glad I bought it.
Perfect summer packing bag..........
ronpenner1240284
Member since
For going light in the summer/early fall this is a great bag. The interior liner of the bag is extremely comfortable and feels great against the skin. Although, this is a great sleeping bag for a specific situation, I would not recommend this bag if it is your only one. If you only plan to own only one bag, go with something a bit more substantial however, for warm weather light packing, this bag is about as good as it gets.
You won't be dissapointed......
Brad Bleak
Member since
People: You won't be dissapointed if you buy the Marmot Hydrogen 30 Degree Down Sleeping Bag, it's so damn comfy that I burned my crappy REI sleeping bag last night...I can't believe the difference, it's the most comfortable sleeping bag I've ever had for backpacking...the last 3 trips have been an absolute pleasure, it packs smaller & lighter then my old bag, more shoulder room, more leg room, makes a great pillow for naps, & it's a Marmot bag (& they are known as the best bags in the outdoor industry)...so take that!!! The extra $ is worth it, just take care of it. :) I don't get cold that easy (usually 2 dogs & hopefully a girl in their with me), but it was 35 degrees when I took a temperature reading & I didn't need to mummy up at all, in fact I had my arms out of the bag...I'm pretty core though, so step off son!
Perfect Summer Bag
Chris Taylor

This bag is perfect for the late spring, summer and early fall in Utah. It is as warm as everyone claims and as light as professed. I own this and the Lithium as well and with these two bags I am covered year round.
