I have used all of the following:
Smith:
Phenom,
Prodigy
Fuse
I/O
Oakley:
Crowbar
Wisdom
A-frame (only tried on not skied with)
Dragon:
DX
Spy:
Soldier
my favorites:
are the I/O's for fit, and peripheral, the venting is decent and they fog no more then any other goggle,
however when it comes to not foging the Prodigy's are fucking bomber, they have never fogged on me. hike 1000 vert ft, no problem. get a pair with the fan and your set.
Crowbars only sell because they are oakley, the look decent, are nothing special, and way overpriced.
