Familiarity: I've put it through the wringer
...you want to go FAST. In anything you do: run, bike, row, even drive (golf balls as well as motor vehicles). Seriously, the first day I put these on I PR'd in my 5k.
In actuality, the functionality of the M2's are unparalleled. Better peripheral coverage than Radar. Better price point than Jawbreaker. Replaceable parts available. And, of course, the clarity of vision that Oakley is known for (NOT just a hype). I truly believe you get what you pay for in performance sunglasses, and these deliver every penny's worth.
