I'm looking for 20 to zero degree synthetic sleeping bag.

I'm willing to spend about $350
Bag must be a long
I need a bag with a 66" min shoulder girth

I'd really like to find one that is as light as possible yet still very efficient.

Any links or help finding a sweet deal would be really cool.

Info on the quality of or reveiws on bags you folks have used would be appreciated.

Thanks for the input!
