What Our Gearhead(R) Experts Are Saying:"I recommend the Flak 2. 0 XXL to anyone with a larger face who has struggled to find a sport frame that actually fits right. The coverage is excellent, the Prizm lens makes details noticeably sharper across different light conditions, and the Unobtainium grip keeps the frame planted whether things are dry or completely sweat soaked."The Oakley Flak 2. 0 is one of the most trusted sport frames ever built, and the XXL edition takes everything that made it great and scales it up for faces that the original left underserved. Every millimeter of the expanded lens coverage is optimized with High Definition Optics, ensuring that peripheral vision is just as sharp and distortion free as the center of the view. The result is a frame that fits larger faces the way the original Flak 2. 0 fits everyone else, with the same proportions and the same performance delivered in a size that actually works. O Matter frame material keeps the larger build lightweight and comfortable through full days of activity, while Unobtainium nosepads and earsocks grip harder as conditions get wetter, maintaining the fit through the kind of sustained output that sends standard frames slipping. Prizm lens technology sharpens color and contrast across sport and outdoor environments, pulling out the details that matter when the pace is high and the terrain is demanding. For anyone who has needed a prescription option, the Flak 2. 0 XXL is fully compatible with Oakley Authentic Prescription Lenses, bringing the same optical quality to a corrected prescription without compromising the fit or the frame.
