Only recently joining the world of sunglasses, POC seems to be coming into its own based on the design of the Do Blade Raceday. The lightweight grilamid frames are larger than other cycling sunglasses, but their memorable shape is about more than just style it ensures you'll have a wide field of vision without any obstruction from the frames that fully surround the lenses. The Racedays feature Carl Zeiss lenses treated with both an anti fog coating as well as POC's Ripel coating, which work together to make sure fog, dirt, and sweat roll right off. The lenses are also curved on both axes for a distortion free view, and they're designed to increase contrast to help make road obstacles easier to see. If you feel the need to change your lenses based on the conditions you're riding in, the sunglasses include a center bar that quickly releases the standard lens for hassle free swapping. The hydrophilic rubber nosepiece is also adjustable, and POC added rubber inserts at the temples to eliminate slipping when you start to get sweaty. A vent on each included lens helps keep your field of vision fog free during slow, hot climbs. The sunglasses noticeably widen at the temples in order to perfectly integrate with POC's Octal helmet, so if you're using the Octal already, the Do Blade Racedays will complete your kit.
