Decent quality ski goggles are the key to avoid fogging. A good balaclava also helps with antifogging - I have a Serius perforated neoprene balaclava that works as well as any.

Find the right pair is key, though. I've used ones that fog up as soon as I pull the balaclava over my nose, or they fog up as soon as I come to a stop.
