The latest edition of the Oil Rig comes with redesigned stem architecture that puts the icon of innovation in the crosshairs of dimensional grooves. Art meets attitude in a style that carries a single continuous lens across contours of lightweight O Matter frame material. Oakley uniquely curves the frame so even medium-size faces get a precise fit that doesnt stick out at the sides. The sculpturally integrated hinges are engineered with dual cam action, and the linear ear stems provide a comfortably secure grip. High Definition Optics (HDO) takes advantage of Polaric Ellipsoid lens geometry to maintain clarity while curving the lenses for optimal side protection and extended peripheral view. The Plutonite lens material filters out every ray of UV, and both impact protection and optical precision meet ANSI Z87.1 standards.
