i dunno why the paint cracked, thats weird, i have never had that happen. my lenses have always been pretty good about not fogging, i have noticed a few days when other goggles were fogged and i was still clear. the only time i got really fogged last year was one day at vail when it was snowing really wet snow and it was cold too, that just sucked all around though. the sick thing about scott is the goggles are relativley cheap and so are the lenses so if your lense does crack a new one is like $30, not $80.
