Nate S.wrote a review of Oakley Flak 2.0 XL Prizm Sunglasses - Men's on June 29, 2016
Familiarity: I've used it several times
Fit: True to size
I bought the Oakley Shallow water prizms a couple weeks ago. In comparison to the Costa 580G I can tell no difference as far as clarity. The Oakleys you are able to pick up water change (lake) better. As far as durability I can`t say for sure obviously Oakley lenses are not glass so they will scratch easier. The most impressive thing about this order was the customer service, I have had 10yrs of experience buying online and James Farnan (gearhead) is the best one to date. Love this company, check their roots and history out.
