Our take on the Oakley Flak 2.0 XL Prizm Sapphire Polarized Sport Men's Sunglasses OO9188 9188F7 59

The Flak 2.0 XL is Oakley's sport sunglass for runners, cyclists and golfers who want wide coverage without a full wrap frame. The XL lens is taller than the standard Flak 2.0, and the half-frame O Matter build keeps it light while Unobtainium earsocks and nosepads grip harder as you sweat. Prizm Sapphire Polarized lenses cut glare and boost contrast on water, road and sky. Against rivals like the Radar EV and Jawbreaker it trades full-frame protection for a more open view and a look that works off the bike too.

Questions and answers

How is the XL different from the standard Flak 2.0?
The XL uses the same frame size but a taller lens for more coverage above and below the eye. The standard version is slightly smaller and lighter-looking.
Are these good for running and cycling?
Yes. The light half frame, wide lens and sweat-gripping earsocks suit running, cycling and golf. The open lower edge gives less wind protection than a full wrap.
What does Prizm Sapphire Polarized do?
Prizm boosts contrast and color separation, and the polarized layer cuts glare off water, road and snow. The Sapphire tint is fairly dark, so it is best in bright conditions.
Do they come with a case?
Yes, a protective soft vault is included.
Will the polarized lenses affect my phone or bike computer?
Polarized lenses can make some LCD screens look dark or rainbow-colored at certain angles. Most phones are fine, but check your devices before relying on them.
Is the frame durable?
The O Matter frame is shock-resistant and built for sport. It flexes rather than snaps under normal knocks, though it is plastic, not metal.
