I should Work at Oakley
Correct me if I'm wrong... but doesn't Oakley's O-matter frames pretty much withstand even a car driving over it (ie: it'll twist up and bend, sure, but it's not going to shatter/snap), not to mention the lens being impact resistant.
The advertised glasses above are $300+ , but I'd rather pay less for most of the standard Oakley, especially since I'm not doing something tacky-ass-hell as using it as a bottle opener.
