Jeff D.wrote a review of Western Mountaineering Alpinlite Sleeping Bag: 20 Degree Down on May 13, 2010
Used for the first time. Very light-weight and obviously very high quality bag. Unfortunately the temperature was between 50-60f degrees and I was too hot. I finally got comfortable around 4 am with the bag unzipped all the way. I think when I get to higher altitude, or the temp drops to around 30-40f it will be perfect.
