Right now it's great weather here in Missouri and I've been having a great time backpacking in the Ozarks.

But soon it will be cooling off at night and that got me to wondering about keeping warm while I sleep.

What I have found is that keeping my body warm isn't that hard. It's my feet that get cold. Even in wool socks my feet are sometimes cold when the rest of me feels fine. It occurred to me that many people probably buy a warmer bag in this situation but I was thinking that some nice down booties would probably do better for less weight.

Anyone out there use booties for sleeping, instead of or in addition to wool socks? How do you like it?
