I just shelled out 15$ for a flimsy pair of snowboarding/ski goggles. REI has something a bit classier but pretty cheap here. They don't fog up and aren't uncomfortable at all. I wore a toque with ear flaps when it got really cold. I also paired the goggles smashingly well with a scarf on still cold days as I'm pretty exothermic, to put it nicely. They're also nice to have if you do other winter sports too.
