Any suggestions to keep glasses from fogging?

[imdoo'n]

seems to work for me, never could wear glasses while riding, went blind (oh the carnage). the fan is not super powerful but moves enough air that they remove the moisture inside the goggles. the goggles will fog up if you put them in the snow etc, but will self clean.
i would recommed them. maybe carry a spare battery, just in case (1 AAA battery)

you can always try coating your lenses with a no fog solution, when i scuba dive we use a 50/50 mix of rubbing alcohol and baby shampoo, just place a couple of drops on your lenses and let it dry. should help by not letting the condensation accumulate on the lens. usually lasts a while when your not under water.....only last 45 mins underwater.

I've had awesome results with colgate toothpaste. Dilute with a bit of water, wax on let dry wax off, usually lasts for one 3 or four day trip. And who doesn't have toothpaste handy
