This bag rocks. It is very light and very warm. It packs very small. I was kind of worried about the narrow focus of the bag on lightness. I wondered if there would be durability or waterproofing issues. I have not had a problem with either. This thing is impervious to the morning dew and so far looks like it will hold up well to life on the trail. I have high expectations for a purchase of this expense, and I really feel like I am getting my money's worth.
