Description
The Hydrogen 30° Sleeping Bag delivers enough warmth for cool-weather adventures and backcountry excursions, yet still keeps base weight at a minimum on light and fast climbs. Featuring Pertex® Microlight on the exterior, its lofty 800-fill-power-down insulation and water-resistant Down Defender treatment will keep you warm and dry. After an epic day on the mountain, give your feet a rest in the roomy wrap-around footbox. Smooth, curved baffles help keep the fill in place, while the nautilus multi-baffle hood with a drawcord, snagless insulated draft tube, and full-length two-way zipper with a zip-guard slider limit heat loss. If the interior gets too warm, use the fold-down secondary zipper to get some air. Tuck small items into the internal stash pocket.

Great buy!!Honestly bought this to be used year round and with a sea to summit extreme 25 degree liner and was more than impressed by the bag by itself! Kept me warm even below the rating to about 23-25 degrees then with liner its perfect down to 15 id say. Love it and will not need or buy another bag unless its another hydrogen!

Warmer Than a Typical 30 BagThis is more like an Uber light 20 bag. At 18F there were only a couple places where my legs were deflating the loft that I felt some cold. But multiple nights below 25 proved this bag for me. First night out was sub 30 and I ended up taking off my puffy cause I was getting hot. It does handle damp well too as I swamped my foot box on a couple occasions on condensation. Yet it kept its loft and warmth.
As a thru hiker, I need a bag thats light and versatile for ever changing climates. This is the bag. It works awesome as a quilt too because of the double zippers. I couldn’t be more satisfied. I’m going to get the helium 0 bag for winter now. Hope it’s as wonderful as the H2.

Ideal Summer Bag!Another great sleeping bag from Marmot. It's light and packs down really small. I wasn't sure how I was going to feel about the extra quarter zipper, but I ended up loving it. It allows me to easily cook breakfast without getting out of the bag when I'm bivying. And, as with all Marmot sleeping bag, it's warm for it's temperature rating.

An Outstanding 3-Season Bag To Keep For YearsThe Hydrogen is an AMAZING sleeping bag. I have used it about 6 times in the past two months and have no complaints. The left zip and light weight make it almost perfect for hammock camping. The only frustration is the same as most mummy style bags in a hammock; most people laying in a hammock tent are prone to kicking out one leg or the other for positioning / balance. The typical mummy style bag does not accommodate that style of sleeping. Marmot does make an excellent product and this bag is no exception. Simple and straight forward in design but excelling in comfort and durability. The stitching is done well and doubly secure in all the places it should be. The zippers are arranged in a way that limits snags and catches for the most part. The material is well selected and is comfortable enough that it calls you to stay snuggled in on a cold rainy morning. The fit was as specified and it compresses perfectly into the supplied bag. If you are looking for a 3-season sleeping bag, look no further. This is the bag you want.

Broken plastic zipperTook my new Marmot Hydrogen sleeping bag out for the first time yesterday. The plastic guard on the main zipper broke. The guard snaps on with two plastic prongs; pretty flimsy stuff. Disappointed in Marmot. I expected better quality, especially at this price point. Now I have to pay shipping to return it.

My favorite mummy bag.Exceptionally warm, comfortable bag! Compresses smaller than the size of a paint can. Lightweight. And I like the color, even if my girlfriend doesn’t. I love this bag, and I certainly fully trust Marmot in the down mummy bag department. Just buy it!

Marmot HydrogenI love the improved zipper, when totally enclosed it is much easier to zip. Often in cold temps, I put my phone in the bag with me to help on battery drain. The small internal pocket is wonderful for this application. First night in the bag, temps dropped to below freezing and I was quite comfortable .
