Kristen,

I hunt in northern Minnesota and the temps can get down there. I' ve found that dressing in layers works well. One fabric I always wear is Fleece. I walk in with light clothes on and then pile on the fleece sweats, sweatshirt, Browning Hydro fleece coat, and I' m set for the day. That fabric is so warm that I can' t walk wearing it without becoming soaking wet in sweat. You can' t go wrong buying fleece.
