The Oakley Flak 2.0 XL is a half-frame sport sunglasses model designed to offer reliable eye protection during a range of outdoor activities. Its streamlined shape and durable construction make it a practical choice for runners, cyclists, and anyone looking for clear vision and coverage on the move.
This XL version features a 12 mm nose bridge that helps position the lenses comfortably and securely, while the 38 mm lens width delivers a broader field of view compared to standard frames. The 133 mm temples (the arms that rest over your ears) provide extra reach and hold, keeping the glasses firmly in place even during vigorous activity. Together, these dimensions contribute to a stable fit and unobstructed sightlines.
Lens width refers to the horizontal measurement of each lens, which affects how much peripheral vision you have; a wider lens offers more side coverage. The nose bridge measurement is the gap between the lenses where they rest on your nose—12 mm here strikes a balance between comfort and close fit. Temple length is the part that extends behind your ear; at 133 mm, it’s tailored for a more secure grip without pinching.
