Oakley Crosshair 2.0, Active wear Sunglasses 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 & subtle sculptural details. The two lenses are cut from a single toric shield & mounted precisely to maintain the original contour. Oakley’s Polaric Ellipsoid technology ensures clarity at all angles of view, & 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.
