Marmot Hydrogen Sleeping Bag: 30 Degree Down

Marmot Hydrogen Sleeping Bag: 30 Degree Down description

The Marmot Hydrogen 30-Degree Down Sleeping Bag provides a comfortable night of sleep at an incredibly light weight. By using premium 850+ fill down and a super-light LightForce nylon shell, Marmot managed keep the Hydrogen's weight down to an impressive 1lb 5oz (regular). In addition to the air-like heft, the Hydrogen has full-wrap hood and insulated draft collar to seal out the cold and assure warmth even when the weather isn't.

This bag is very small, light and toasty down to the mid 40s. I haven't used it at the 30 degree rating yet, but I should have the opportunity in a couple of weeks. It's also very roomy, which I like.

I had originally purchased a Western Mountaineering 30 degree bag but returned it as it was rather small in the shoulders. That bag also seemed to sacrifice a lot in terms of durability to save on weight. The Marmot Hydrogen bag is the perfect balance between weight, compressibility, warmth and comfort. The long version still packs down to something just a bit larger than a nalgene, and the weight is negligible. I have plenty of room to roll around in it and it has already held up well in Buffalo, NY early spring, which is none too warm at times (temps around 35-40 F at night). I have the sense that this bag would do well even below the 30 F rating.I've used a lot of bags meant for cool to warmer nights and this is by far the best I've seen.

I'm 6'2" and have plenty of room in the long. Slept comfortably down to the temperature rating, weighs almost nothing and packs down to the size of a loaf of bread. Great summer backpacking bag.
