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. Sporting top-half frames coverage, these open-edge design sunglasses are a combination of enhanced style and performance. 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. Shatterproof and scratch-resistant Plutonite® polycarbonate lenses provide added durability, while meeting all ANSI Z87.1 standards for optical precision and impact resistance.
