Randall Flagg wrote a review of Oakley Flak Jacket XLJ Replacement Lenses on August 31, 2011
I just bought a set of Flak Jacket XLJ VR-28 black iridium lenses for one of my pairs of Flak Jackets. I love them. They provide a great color (very much like Maui Jim rose) and the contrast is excellent. They are designed to work well in lower light but they also perform very well in bright sun. I wanted something for hiking where you are in and out of trees and therefor shade and these are just the ticket. They are my favorite lenses for the Oakleys. The clarity is awesome.
