The county comm bags have a zipper down the left side, with a draw-string mummy hood. They are tapered slightly at the feet.

They have a tag on them (like a mattress tag) that says the finished size is
80x30x20 with 1.6 lbs of filling.
The registration # on them is CA3856(CN)

Short of a wiggy's bag, this is the best deal I've seen on something like this.
