I have a marmot wind river long 600 fill down with very similar specs I would sell you for $110 plus shipping. Almost brand new in excellent condition if you are interested. The main difference is the wind river does not have a hood, but it is a long so you can scoot down in the bag and just about cover your head or wear a hat when it gets really cold.
