After going insane over the amount of goggle choices available, I went w/the Olive Military/Black Iridium style. Broke them in on a bright sunny day @Park City Mtn., and they worked like a charm. No fog up at all! Next day in snowy conditions @Snowbird was amazed at how clear & defined everything looked. Day 3 @Deer Valley was overcast but the lenses did the trick of keeping everything focused. Strap went perfectly over my helmet, the interior fleece padding felt great on my face, and the venting system does a wonderful job of keeping the lenses fog-free without freezing your eyeballs! I have a larger dome than most, but these fit my face perfectly, & with no gapping between them and my Giro helmet. Due to the expanded lower viewing angle there is a very minor bit of reflection if used indoors (trying them on), or staring at the sun. Although I'm a person that is bothered by the tiniest scratch on a lense,fingerprint smudge,etc..., the reflection didn't distract or bother me at all. Hope this helps narrow down the decision process for someone!
