Marmot Atom 40 Degree Sleeping Bag
The Atom's ultra-light design and our highest quality down have given it cult status among alpinists as a bivvy bag on extreme climbs, but its comfortable, silky fabric make it a great bag for warm-weather bivvies on casual summer road trips as well.

Bigger on volume and warmer than expected.
I ordered the LONG for extra room. My overweight 6-1, 250 pounds fits comfortably into the bag. Not too tight, not too loose and just enough wiggle room. I was "concerned" when the bag was stuffed for two nights and didn't return to its original (out of the box) loft after that. However, on its 1st night out at 38F, I found it to be sufficiently warm with only a silk weight pair of long johns and no socks. I have easily cut my volume and weight in half by switching from a synthetic 40 to this well made down 40. Sprinkled water beaded well on the surface and the zipper is trouble free. My first impression and first night out leaves me with only positives and no negatives.
