Best. Goggles. Evar.
I have the older model, with a dual thermal lense in them. I rarely have to turn on the fan, even on the most humid days, and I sweat like a bastard. I've had them for years, and while I've quite often heard people bitching about goggles fogging up what do I do? Shoot them. Because I can see.
