I found it extremely difficult to change lenses and especially to get the right lens to fit properly into the slot. I contacted the company one time and received a replacement, but it was only minimally better. Also, the frame seemed warped and didn't fit on my face correctly. I even went back to a Bolle dealer and he tried to bend the frame back into shape, but it really didn't work. I rarely wear the glasses anymore.
Pros: good visibility
Cons: Difficult lens changing, crooked frame
