RE: What are your layers?
For cold weather I like a set of wicking underwear. Cabelas Under armor knock off's or Under armor are my favorites. I then like either fleece or wool pants or bibs with a shirt made of the same. Then a nice heavy fleece or wool vest with windstopper material. Then my outer layers. The same treatment for my feet, wicking socks and 1 to 2 pair of wool socks + a good pair of boots.
