Ok let's see if I can give you a couple tricks to help you keep warm (weenie..lol). First, I think the double layer of cold gear could be your problem. That stuff needs to breath. Try wearing just one with the duofold over that.
Now for my trick when it is actually cold (not 30*). Use an Ace type bandage or a back support and put a heat pack behind you on each kidney. Then get the "toasty toes" and put them in your boots between your polypropolene and wool socks. Get a couple moe hand warmers and put them in your coat pocket or inside your glove.
Good luck.
