    Excellent quality for the price. Purchased as lighter weight alternative to Marmot Helium 15 degree bag that I LOVE. Next big trip will be in August, and this bag compresses much smaller and weighs a pound less.

    I've owned my Marmot Hydrogen for some time now and can say that I honestly love it. The temperature rating seems to be conservative! I was nervous at first that this bag would have a hard time pushing into the low 30s, but can now say that I have comfortably cowboy camped down to 25° with minimal layering (just wool socks, wool hat, light poly base layer). I wouldn't suggest this to anyone (I made sure to have plenty of other layers with me, but I found I didn't need them!), but it is totally possible. Very versatile bag for long trips through varying nighttime temps as low as 25° with some layering.

    The cut is roomy but not as long as some other comparable bags. I'm 5'10", 170 lbs and I'd say the bag "just fit" for length and was plenty roomy at the shoulders and hips. I've slept on my back and side comfortably

    The hood is possibly the greatest of all comparably priced bags. It covers the face well and can cinch down to just a mouth-sized opening, with plenty of room for a small stuff sack pillow behind my head. I found that I lose very little warmth to the outside when even just slightly closing the hood. Also worth noting is the relative ease of operating the hood adjustments.

    The zipper works well and snags rarely.

    The outside shell does a fantastic job of blocking wind while cowboy camping.

    I'd recommend this bag to anyone pursuing long hikes/trips through variable temperatures above freezing, with occasional/rare nights just below freezing, where weight and cost are important. 25 ounces for under $250 (bought on sale) is really pretty spectacular.

    A++
