CRUSHER 6 - GLOSS LIFETIME WARRANTY offers maximum front & peripheral protection with surf infused design. High Gloss black frame, gun metal logo and grey Impacto lenses by Carl Zeiss Vision make CRUSHER 6 the most intimating style in the collection. "Bruiser", "nasty" & "bully" are a few words that sum up the muscle of this ballistic masterpiece. We don't recommend rock crushing with these sunglasses but it is cool to know you can.
