Wool on the outside with fleece and layered level 4 underneath. It will wick the sweat away so you don't get cold when you slow down. Plan on putting clothes on and off throughout the day depending on your activity. My feet are always the first to get cold and when they do, it doesn't matter how much clothing you got on, your going to be cold and my boots are 800 gram thinsulates. Little bit on the heavy side but keeps me warmer than most. Good luck hunting.
