Achilleswrote a review of The North Face Superlight Sleeping Bag: 0 Degree Down on August 21, 2007
I used this bag in Grand Teton National Park the first week of August 2007. I'd say it was in the 30's or 40's at night and I was, not surprisingly, very warm. I was concerned about the tent condensation because I only had an upper body Therma-rest and I was sharing a small tent with another person. Two of the mornings I woke up and the outside of the bag felt wet but it was still warm and cozy inside. A good night of sleep was well worth the hefty cost of this bag.
