The XLJ version of our Half Jacket frame offers extended lens coverage for larger faces or for those who prefer an expanded field of view. These unique sunglasses let 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.
