I will be wearing under armour, a thermal army long sleeve shirt, then 2 cotton long sleeve and 1 mossy oak long sleeve button up. Just regular mossy oak pants. I have thick coveralls that are totally awesome. I will wear a thick thermal face and head cover and thick insulated army gloves. Should be good to go. I've been out in colder weather with this same gear and have been just fine. Plus my cold late season hunts only take in the last 1 1/2 hours of legal hunting time so it's not like I'll be out there all day. I'll be good to go.
