Marmot Hydrogen 800 FP Down Sleeping Bag Long Left NWT I bought this bag a little over a month ago on impulse, then realized I really dont need it and probably wont use it much. I removed the tags and tried it on a few times. It is new and perfect, except the decal with temperature limits was already flaking off when I first took the bag out of the box. It has a lot of loft for a 30°F bag, almost 4 inches, and the EN lower limit is actually below 25°F. The EN extreme limit is for dead people. The info below states that the bag has 13.8 ounces of 800 FP down, but the tag on the foot end says 13 ounces. I believe the tag. This is the latest iteration of the Marmot Hydrogen bag, which has curved baffles, a second zipper, and improvements to lessen the likelihood of zipper snags. The bag actually weighs a hair over 25 ounces on my digital scale, which I think is amazing for a bag with so much fill and loft. The original tags, storage sack and stuff sack are included. REI has good, complete information on their products, so here is their blurb about this bag.
