Built for performance, these irregular sunglasses from Oakley may look stripped-down and simplistic but they in fact harbour a wealth of technical features. Their interchangeable lens has been tested to stand up to high-velocity impact as well as being moulded into a single contour to increase your peripheral vision. With three extra-grip points on the earsocks and nosebombs, these glasses are created to protect you against the sun and wind even during strenuous and turbulent activity.
