If you’re looking for a classic, ultra-light sleeping bag, look no further than the Marmot Hydrogen 30. This 30 degree sleeping bag is filled and finished in Santa Rosa, CA with 11 ounces of high loft, certified 850+ goose down. This Marmot sleeping bag has a classic look with a full-length zipper and stretch tricot, full baffle construction. The baffles allow for some down shifting, so feel free to push a little extra down toward your cold spots, while the stretch tricot makes this down sleeping bag almost bombproof (we’re talking tons of strength and durability). Marmot took more control of down shifting when it came to the head by adding a six chambered Nautilus hood to provide a close, cush fit. This 3-season sleeping bag comes equipped with an overstuffed, insulated draft tube, Velcro-free face muff, snag-killing zipper guards, DWR coating and you even get a stuff and storage sack. The Marmot Hydrogen 30 Sleeping Bag is sure to become your old standby for cool weather adventures, spontaneous sleepovers or nights out on the lawn.

reliable temp rating, compresses to smaller than your headMarmot makes great stuff - unlike some manufacturers they test their products with an outside lab (in Norway I think) and provide an standardized EN temp rating. The result is a bag that is true to it's temp rating. With a compression sack it shrinks to smaller than your head. Mine at least...,,,,My only complaint is the continuous baffle which is a blessing and a curse - because you can shift the down around 360 degrees in the bag you can make it warmer or colder. The flipside to that is if you use the bag a lot (think through-hiking) you're going to have to keep adjusting the down to eliminate cold spots. Great for the weight conscious.

Great bag for BackpackingI got the long because I am 6'-3", 210 lbs and it is a very comfortable fit. I considered the mountain hardware phantom series of sleeping bags and chose this one due to the extra width in the shoulders and hips. So far I have slept under the stars in this bag in 40 degree F and was very comfortable with just shorts on. I use the XS Sea to Summit eVent compression dry sack for packing and it squishes down smaller than the size of a volleyball. The zipper is full length, but it does not unzip the foot box. I wear a US size 13 Men's shoe and the foot box is plenty big enough. The bag does ventilate very well in warmer weather.

Great 40 degree bag but not 30 degreeI wanted an ultralight down bag, comfortable to 30°, to camp at 12,000 foot elevations in the summer. The 30° Marmot Hydrogen seemed to fit the bill. On 2 nights it got down to 37°. It was a cold night’s sleep. On Marmot's website they rate the bag 39.2° for a comfortable night’s sleep, 30° at the lower limit. While I would have made it at 30°, it wouldn’t have been a good night’s sleep. I like everything about the bag except being cold. I am going to get the Marmot Helium, a 15° bag with a comfort rating of 27.7°. These are both great bags but if you like to sleep warm in high country summers and do ultralight backpacking, go for the extra 4 oz of down and get the Helium.

Awesome Bag!I purchased this bag last spring, and wanted to use it for an entire season before I cast my judgement. Bottom lines: Durability, Despite the bags thin light weight shell material, it has held up to several nights in the bivy sack, several more in a tent, zipper snags (operator error), and a couple nights on a friends floor with my dog. The marmot rep also informed me that they keep shell material on hand for every bag they have ever made at the repair shop, just incase! Temp Rating, as other reviews mentioned Marmots bags are independently rated, personally used the bag comfortably into the mid 20's. Roominess, the regular has plenty of space for me (5'11" 170lbs) and some clothes.

My first down sleeping bag - a fan forever more!This is a review of the 2007 model. Used 100+ nights.,,I was a bit weary as to whether a bag weighing as little as this could keep me warm or not. Turnes out I didn't have to worry. In the buff, using only a silk liner, I slept like a baby down to about 0 C. At -5 C I slept, but woke up cold a few times during the night. The temp rating seems to be accurate.,,I had my bag sort of ruined when I had it cleaned by a "pro" who didn't know what he was doing. He didn't dry it properly, so the down got clumped. Having it cleaned again, by someone who knew what they were doing, it's almost OK again, but is now only warm down to about 5 C. So, make sure your cleaner REALLY knows what he is doing.

Not a bargain, but worth the moneyThough I have not had a chance to use it as the weather has not cooperated, it is a great bag ... I can't wait! The bag has a full length zipper which a great advantage over the previous model. There are 2 zipper pulls so that you can have the top closed and the bag open near the legs. If you are like me, this is extremely important. The bag lining is super silky I wish I had sheets this nice. The material quality seems to be very good. The hood portion does wrap cinch around your face nicely ... perfect for a cold night. Did I mention that it is super soft and silky? The zipper works smoothly. The bag that comes with the sleeping bag is huge ...it is not the litte bag shown in the

This bag is phat with a p annd an f!This bag is fookin' nice! The liner material is so silky smoove. Tried it out in the rogue siskyou national forest here in southern oregon. Temps got down in the low 30's. With a thin base layer, in my tent, I was nice and toasty. I am sure it would be comfortable at colder temps. Also much more room in the shoulder area than other ultralight bags. 62" as opposed to 60" with most others. Full length zipper is nice also. To use a phrase my grandpappy used to say, "This bag is cooler than the other side of my pillow!"

Better Bags AvailableI used this bag for a 10 day trek, with temperatures as low as 40 degrees. I was warm almost every night except one, when it rained. Condensation dripped on the end of the bag by my feet, and it was cold the rest of the night. That wasn't a huge problem however. It was incredibly light for a 30 degree bag, and packs down to a very small size. I would recommend buying the ems velocity instead, an ounce more but it's synthetic.
