Classic meets contemporary in CROSSHAIR? 2.0, the latest rendition of a lightweight C-5 alloy metal frame that merges classic aviator design with a contemporary lens shape and subtle sculptural details. The two lenses are cut from a single toric shield and mounted precisely to maintain the original contour. Oakley?s POLARIC ELLIPSOID? technology ensures clarity at all angles of view, and optical precision meets ANSI Z80.3 standards. Jacketed with UNOBTAINIUM? to increase grip with sweat, the sleek stems are part of a comfortable Three-Point Fit that gets a dose of dimension with icons that integrate with the hinges.
