Goggles got to be the worst piece of kit to get quality fog proof, but one of the most important to have a good game.
My Civvi job is in the Harley industry, they sell all kinds of top line "expensive" fog proof goggles and lenses, also wipes.
they all work "marginal" and some of this stuff is $150 a set, I have worn different goggles in the military, again they work marginal on their own.
I sweat a lot and steam seems to come off my face in any weather, the set up I have now is a cheap $18 set of low profile goggles I bought through Evike and I installed two fans, problem solved. (I also have a spare set incase the worse happens) total investment for two complete sets of brand new goggles with fans, $80.
I cant see spending more than $40 on a set of goggles that I have to put fans in anyway for them to keep me fog free, the $80 + goggles will be a little more effective but they all get scratched the same and will eventually fog if you are sweating and or in humidity that is high.
buy a set of goggles that you can see out of well, then add a couple fans with a 7.4 lipo and enjoy the game.
but the goggle saga will continue
