Replying to Fog between google lenses

anyone know a good way to get rid of fog between your lenses? Its such a bitch, all day long i couldnt see shit out of my googles and it was windy and snowy as fuck so i was pretty much blind in the alpine. I tried going in to the lodge let them clear up, and they did, but then they went right back to normal as soon as i went out. Then i tried using a hand dryer in the lodge like i read in that tip thread, same thing, cleared up and then back to normal as soon as i went back out. I never wipe the inside, not that that would have an effect on this situation, and i have smith i/os which everyone claims to deal so well with fog, but honestly my eg2s fog up way less...so any ideas?
