By wearing a balaclava over your face it will heat up your breath and in turn keep your face warm. Wearing inexpensive goggles completes the picture and blocks the cold air from freezing your eyeballs. I ride in single digits and I'm completely covered from head to toe. My goggles do fog up at times, but I'm still trying to solve that problem. Dishsoap seems to work the best, but it still fogs up at certain cold temps. Ebay has some nice thin balaclavas nicely priced.
