In the deep south, it isn't the cold, it's the bugs, as I'm sure many of you know. I got a light weight, camo mosquitonet shirt for hunters, at a guerilla store near Orlando, FL. Also got several yards of nylon net from the local fabric store. These are right up there next to T-paper on my list of importance. It's not just comfort, it's that you get no rest if you have to worry with bugs all day and night, and rest is very important in a survival situation.
