Kenneth K.wrote a review of Oakley Flak Jacket XLJ Replacement Lens on November 20, 2012
Familiarity: I've used it once or twice and have initial impressions
I am not even sure when it happened but there is a big scratch on one of my lenses the first time I wore them. I usually get replacement lenses once a year and they seem very durable. I hope these are real Oakley replacement lenses.
