Rob Fleming wrote a review of Marmot Trestles 0 Sleeping Bag: 0 Degree Spirafil on June 27, 2010
For everyone wondering, i can get the regular size bag to compress down to 12" with a 9" diameter in the sack provided.
I am a very cold sleeper and this bag is Toasty. It is pretty bulky, but that just makes it extra comfortable to sleep in. The zipper snags bad if your not careful. At this price for a 0-degree bag it was easy to overlook a little inconvenience. It also has a little zippered pocket close to your face on the inside which easily fits a recently recalled 1 pound can of spaghettios with room for a clif bar or two.
