Jay Swrote a review of Western Mountaineering Alpinlite Sleeping Bag: 20 Degree Down on September 28, 2011
Only used it twice but I love the fit. I'm 5'-2" and the bag fits perfectly with some room to spare for extra layers at the bottom.
My first trial was at the base of Mt Washington and the outside temp had dropped into the low 30s. I was cold with my base layers on but I run cold.
The second trial was in VT and the outside temp was in the 50s and damp. I was a bit too warm in the base layers on but boxers & undershirt was just right.
The only downside I experienced with the bag is the smell it gives off in damp conditions. The down smell can be a bit much even if the bag isn't directly wet.
Overall love the bag!
