Got these down throws at The Sports Authority on clearance for $9.99 each.
Once unpacked they actually puff out pretty good. They are sewn through baffles, and after sitting out of their stuff sack for a minute loft to about 2". The fabric leaves a little to be desired, but they weigh about a pound. I plan to put a couple of darts in each side and put grosgrain channels into each end to run shock chord through.
I'm gonna say 35 degrees or so comfort level. I might put a nylon shell over one side with a slight droop to it to create a thin air pocket and wind block.
They don't sell them online anymore because they are discontinued, you'll hve to go by your local store and check em out.
