Mills casually pairs smooth, understated style with all the premium technology you expect from Giro. While the medium-to-large fitting, Italian-made frame will have you reaching for Mills, it's the optical clarity of VIVID Technology that will make this eyewear your favorite for years to come. We partnered with Optics by ZEISS® to create this patented lens technology, and you'll notice the difference anywhere from sunsets at the beach to midday on the glacier. Other premium details include stealthy rubber grippers on the nose and ears (to keep Mills in place when the going gets wild) and three-dimensional Giro logos to let others know what makes you tick.
