Quality glasses. My only complaint is that they are made in China, not Italy (but the quality does not seem to have suffered from the manufacture location - yet). Be advised, these are "cockpit" not "aviators" - the design is the same but the lenses are smaller. If you have high cheekbones like me this makes them far more comfortable...
Overall, great product. Looks stylish, seems quality, but a little delicate. I'm worried about crushing them more then other shades I've had. Great optical clarity. They feel comfortable and stay on well. No complaints....also, this was the best price I could find. They were $190 in stores. HDO had great customer support as well.
