saga facetubes never fog up and easier to breath through but still protects you from the wind, I wear to facetubes, one over the other. easy to breath through, comfortable, protects from wind adn still looks dope
For warmer days I just use a bandanna, no goggle fog (i do have oakley goggles) and usually no freezing. For colder days I have a seirus mask and it doesn't freeze nor does it fog my goggles. For days in the middle (too cold for reg bandanna or too warm for full mask) I have a fleece bandanna which doesn't freeze either. But as stated above, Oakley goggles are the way to go because they have a real good anti fog coating.
