Thanks for the tip if/when i buy a helmet...I don't wear one and my goggle fogging is definitely due to the heat/sweat production...plus i live in a coastal climate...lose/lose for clear goggles...

I'm a heavy heat producing machine, sweat a lot and ALWAYS had foggy goggles untill I switched to Smith fan operated units. Changed the game for me. There's still condensation that forms on the top...
