I've had these for almost a year now, they endured an entire season guiding in Moab, then I took them to a concert and they got stepped on when I set them down. very stupid of me, yes I know. Aviators usually aren't very good at staying on your face but these are excellent. I especially like the additional coverage from the oversized lenses, no matter where you look you eyes are protected form the sun. I wish Smith would make them out of indestructible titanium, hint hint, because they are somewhat succeptible bending.
