Oakley BOTTLECAP offers a comfortable fit on all facial sizes but is especially well suited for small to medium-size faces due to contouring that eliminates the wide corners of conventional frames. Patented XYZ OPTICS® maintains razor sharp clarity, even with lens curvature that opens peripheral vision. Oakley's HIGH DEFINITION OPTICS® (HDO®) combines patented optics and PLUTONITE® lens material that provides 100% UV filtering and unsurpassed impact protection. This durable optical instrument also provides 100% UV filtering and impact protection that meets all ANSI Z87.1 standards. Its sculpturally integrated hinges are engineered with dual cam action and finished with true metal Oakley icons.
