SlowMoSamwrote a review of Smith Serpico Polarized Sunglasses on August 2, 2011
These are fantastic sunglasses and I highly recommend them. They're light and the wraparound lens is key. Because I'm a freak about my sunglasses, I store them in a hard case when not in use. Unfortunately, the arms of the frame that go over the ear have worked a fairly pronounced scratch into the inside of the lenses and the scratch is directly in my line of sight. I've had these glasses about 1.5 years and it's just recently become obvious, which isn't terrible, but still a minor annoyance.
I'll probably send them back to Smith for warranty.
