I'd be looking at a Western Mountaineering bag that fits you... you can get something with a gore windstopper shell to handle external moisture if it's a concern, or just take along an over-bag.

While there are other good bags, I've been using WM bags for 25 years and wouldn't use anything else. We currently have three in the house...
