Ricky Lyman wrote a review of Kelty Light Year Sleeping Bag: 20 Degree Down on March 20, 2011
This is an amazing bag, its very compressible (to about the size of a soccerball) and I experienced no problems with the provided compression sack. And the provided storage sack makes a great pillow when filled with a jacket and other misc. cloths. The only thing that I'd say is a bad is it isn't quite a 20 degree bag, at about 30 I had to throw on base layers. But the good definitely out-weights the bad as winter camping isn't my gig.
