The farther away from the skin I get, the less technical the clothing gets when it's cold and relatively dry out. A balaclava is great under the helmet, and a wicking top followed up by fleece layer(s), old ski gloves, some REI long johns, old sweat pants, wool socks and the same shoes I wore in the summer worked for me until I needed to put a windbreaker of some sort on when it got really cold.
