Top rated in review of lightweight bags (http://www.backpacking.net/gear-reviews/sleeping-bag-review/):
A great 30 degree bag with ample room for a fully clothed me (at 5 foot 9 inches tall and 170 pounds) which makes it useful at even lower temperatures.
The Hydrogen is cut a little wider than the WM Ultralite, so if you might feel constricted in the Ultralite's narrow confines, I suggest trying this bag as your next option.
The Hydrogen's shell and liner are crafted from relatively durable 1.2 oz./sq. yard ParaLight DWR 30 denier yarns used with abrasion and tear resistance in mind. The feel of the fabric suggests that it, along with the fabric used on the Big Agnes bags, is the most durable of the bags in this review. The Hydrogen has an excellent DWR application. Marmot uses stretch tricot baffles which provides strength, durability and good down control. Marmot's velcro-free face muff design is the best. The muff keeps the drawcord and zipper away from your face and provides a snug, comfortable fit of the hood as it is being tightened. I get a snug fit well in advance of the hood being closed all the way. The hood drawcord is positioned for easy access yet remains out of the way.
Zipper guards, second only to the Western Mountaineering bags, help repel biting zipper coils. Smaller and shorter zipper to minimize weight, 38" long. One hang loop on outside of foot box-- the bare minimum. Generously down-filled draft tube significantly minimizes cold leaks through the zipper. The baffles are continuous down to the middle of bag (at zipper's end) so that down may be shifted in response to the weather conditions. The baffles are side blocked below the end of zipper which keeps the down in the lower part of the bag evenly distributed. Classic trapezoidal foot box for more foot room.
