Serengeti make nice glasses, but their QC is poor, and their support is worse. I bought a $200 pair of large aviators and after wearing them about 10 times, a lens popped out while I was putting them on. The lens shattered into 5 pieces when it hit the ground. The glass is obviously not shatterproof - or even very strong. The store said it was my fault for not "maintaining" the glasses and I would have to pay $150 for two new lens. I told them to keep the glasses. Serengeti did not respond to my complaint. Since then I bought a pair of $28 Dockers from Sears and they are just as good as the Serengetis anyway.
