Just got these in time for a weekend trip to Slovenia. Worked terrifically on the first day, clear skies. Not so great the second day, cloudy/low visibility. Only had them fog a little on the top when i put them up on my damp beanie for 15-20 mins. Got these from Tramdock and they came out of the box with a small scratch.
Only con: where the band and goggles come together, the piece stick outward and makes the goggles look too big.
