With its interchangeable lenses, the Oakely Flak Jacket XLJ OO9009 sunglasses is perfect for any sporting environment. The many available lens colours all feature the clarity of Oakley’s High Definition Optics. Two different sized nose pieces are included, and like the stem sleeves, they’re made of Unobtanium to increase grip when in contact with perspiration. The frame is made of Oakley’s lightweight O Matter Oakley’s Three-Point Fit removes the need for curved ear stems, giving a sleeker overall look whilst not compromising on practicality and the semi-rimless design means there’s no frame blocking downwards views. This frame is also available with polarised lenses, along with the standard Plutonite lenses, both with block 100% of UVA, UVB, UVC & harmful blue light up to 400nm.
