RE: Im through with hunting...
Wool, wool, wool....
Broke down this year and bought a wool parka and have been extremely warm during the cold mornings we've had recently in Central IL. Also, the foot warmers that you place on tips of your toes work great. I think they are $.99 at Wal-Mart. Others have mentioned it, but stay away from anything cotton. Fleece and wool have worked great for me this year.
