This thing packs down to about the size of a volleyball, weighs under 2 lbs, but still keeps me comfortable and warm at night. Highly recommended. I got it a little over a year ago and have slept at least 45 nights in it (including a 3 week stay at a field lodge). It immediately became my favorite bag and I look forward to many good years in it.
Only complaint - the zipper stops about a foot or two before the bottom of the bag. This makes the bag lay a little funny when I poke my feet out the bottom in warm weather. Still, it is a great bag.
