Oakley Half Jacket- The Half Jacket is Oakley’s first dual-lens eyewear with interchangeable lenses, this chameleon lets you adapt instantly to any light condition. When the sun fades or flares, switch to a new set of optional lenses and change your entire point of view. Or just enjoy the freedom to customize your look instantly. Accented with true metal icons, the lightweight O MATTER® frame includes UNOBTAINIUM® earsocks and grip anchors. The open-edge design extends your vertical field of vision, and each set of optional lenses retains the peripheral clarity of XYZ OPTICS®. That’s just one of the patented innovations that give HIGH DEFINITION OPTICS® (HDO®) its unbeatable performance.
