These things rock. I have been an oakley fan for the last 11 years or so. Never been disappointed. I got these because my new job need more wrap around eye protection. I had a pair of half jackets that I was very happy with but they were 3+ years old and getting tired. These glasses give me ANSI Z87 rated protection from flying debris and keep me stylin'. The polarization is a plus to keep glare down when I'm off playing after work.
Bottom Line: Buy them. If you can keep a decent pair of shades around then this is what you need!
