I've had these for about a year and a half. The best glasses I've ever owned. Very lightweight, but sturdy. One day while out biking I tucked them into my shirt, they fell out and landed in cinders underneath the bike and I rode over them. I was sure they would be totally ruined, I actually had to push a cinder out from between the lense and the frame. Incredibly, they weren't even scratched!!! I'll never own anything but Maui Jim from now on.
