IdahoHiker, I just ran into this: Everything at REI Outlet is 20% off the sale price through January 29. That includes the Men's REI Sub-Kilo--here's the URL for the Long (they have the regular, too): REI Sub-Kilo bag--long

At ~$136 plus shipping, this is a steal! It's a better bag than the Campmor 20* bag we've suggested, but about the same price. It's not quite the $85 that some people have been getting in some of the stores, but it's still a really good price! Not a top quality bag, but a good intermediate bag. It should meet your needs for quite a few years. Do check the specs for girth, measure your own over an insulating jacket, to make sure you'll fit inside.
