Dakota Chapman wrote a review of Big Agnes Lost Ranger Sleeping Bag: 15 Degree Down on June 2, 2011
I am a Backpacking guide in Colorado. this past week I went on a 7 day 6 night trip with my fellow guides. This was the first time that I actually got to try out the bag in cold temps. each night was below 30 degrees. We were sleeping on snow each night. Overall I was not satisfied at all with this bag. The liner is not very water resistant at all. If you are looking at this bag you should know already that real goose down does not insulate when wet. And this bag with the pad that gets put in the bottom creates extremely cold air spots that are impossible to keep warm unless you put an 850 fill down jacket on your side. I am 6' 4" 230 lbs and I was still cold. I am very warm blooded and I froze every night. Unfortunately not satisfied at all.
