This frame is metal and plastic and is well made. The design is out there and you either like it or you do not. You can change lenses and there are various after market manufacturers. This was an awesome buy in my humble opinion.
This was a gift for my son. He was pleased with them but disappointed that the "O" was not on the lens nor Oakley on the piece across the nose like his old Oakley's. In addition, there is no case which was stated in the sale description.
