I have the Klim F4 helmet and use Scott Goggles.
Seems to work very well. I do not have to use a No-Fog, just the breath deflector that comes with the helmet. If it is cold, I use a Klim balaclava with the goretex windstopper, otherwise no balaclava and let the helmet breathe like it is suppose to.
Works for me!
