Ryen O.wrote a review of Big Agnes Blackburn SL Sleeping Bag: 0 Degree Down on September 3, 2012
This bag is very nice, light and very warm...on the top half.I have slept 13 nights in it, and if you do not have an insulated pad you will literally freeze your butt off! The foot box on this bag is wider than most bags which is nice if you don't like your feet tied up and trapped. The zipper is nice, it will snag, but I haven't found a single no snag zipper sleeping bag that doesn't. As far as warmth goes, I have slept in 9 degrees in a BD Firstlight and ended up having to unzip because I was too hot. Great bag, BUY AN INSULATED PAD WITH IT!!
