Oakley's XLJ version of our HALF JACKET® frame offers extended lens coverage for larger faces or for those who prefer an expanded field of view. This Chaneleon of eyewear was Oakley's first dual lens eyewear with interchangeable lenses. The open-edge design extends your vertical field of vision, and each set of optional lenses retains the peripheral clarity of XYZ OPTICS®. The lightweight O MATTER® frame includes UNOBTAINIUM® earsocks and grip anchors. That is just some of the patented innovations that give HIGH DEFINITION OPTICS® (HDO®) its unbeatable performance.
