I just saw a nice oversized (40 x 84) rectangular bag at Bass Pro Shops for $49.95 this weekend. It is rated to 0 degrees and the outside is a decent duck canvas. Not a backpacking bag, but definitely a decent elk camp bag. I can't recall the mfr, but in any case it was what I would class a very good deal.
