I swear by the Underarmor Coldgear stuff. Its hard to believe that something that thin (it's not much thicker then Spandex... great for terrorizing your teammates in while getting changed...) can do such a good job of keeping you warm. When it's below freezing, I usually just wear the Coldgear and my BDUs. If it windy or wet out, I'll throw on my Gore-Tex stealth suit under the BDUs. That takes care of just about everything with a minumum of bulk.
