cold cold world packs are perfect. Randy Radcliff makes them in the Mount Washington Valley in New hampshire (not far from where wild things packs are made) I have the valdez and chernobyl. Love em both. I tend to pull out the chernobyl more, and its really an amazing pack. Everyting you need, nothing more. I think to use it as a bivy would suck, but could be done. But a forced bivy shouldnt be comfy. Get the CCW.
