JCNwrote a review of Oakley Flak Jacket XLJ Sunglasses on May 1, 2008
Check the Transitions, they are great. I ordered the jet black/persimmon trans and they quickly replaced my smiths as my new favorite lenses. I thought smith knew what they were doing when it came to lense quality, but these Transition Flaks are far better. Water, sweat, oil and pretty much any other thing you could think of just beads off of these bad boys. I love nice glasses and think that any active person should treat themselves to these Flaks. I have a medium-sized face and the XLJ's are fine. Check out the Oakley website to see what the different lenses are capable of doing in various conditions. They have a nice little interactive site set up for lenses.
