These glasses work great.
Bought these glasses for my brother. He's used them on three different skiing trips and he loves them. The fit is great and comfortable for his big head. The extra lenses are easy to change. The only downside is the extra lenses don't fit in the slots within the case.
good shades
I have a pretty small face and these look pretty good. Come with a cloth storage bag. Polarized lenses are nice. They tightly grip the side of your head, i plan to use them for cycling. I'm not a huge fan of the color but overall i'm happy.
Nice glasses but beware. . .
Not all versions come with multiple lenses. I got the flat black "Evolve" which are made, at least in part, with recycled materials. They only came with one set of lenses.
