I'm 5'3" about 115 pounds and sleep very cold. Open to suggestions on bags but I need something that will fit in a small pack, is very warm, and used (if down). I'm open to synthetics, but so far it doesn't seem like a synthetic bag will meet my needs. Weight and warmth are very important to me since I'm small.

Id like to do part of the AT next year so I need something that will be warm enough on the coldest and highest parts of the trail. If you think my EN guess is off let me know.

I'll make additional separate posts but I'm also looking for a light head lamp and sleeping pad for the same purpose. I'm fairly new to this and am not sure about an open or closed cell pad or other options.
