I'm used to Hunting in cold weather when I travel out of state and always dress to be warm depending on how mobile I am. If sitting, I've always dressed very light and wore a heater body suit in conjunction with a lock on stand. Now I have a tree saddle I'm gonna use and what to know what y'all wear to stay warm for long all day sits in a tree saddle. The heater body suit is not an option given how it zips up. I'm talking mid west temps like early November for Ohio, Indiana, and Illinois.
