Big without being bug-eyed and tough without being heavy, the POC DO Blade Raceday Sunglasses are the shades you need to complete your kit. They've got some of the biggest lenses on the market and there're no frames to get in the way, which means the field of vision is unsurpassed, but the lightweight Grilamid plastic ensures that they don't feel like they're giving your nose and ear muscles an annoying workout. Cut by the legendary masters at Carl Zeiss, the lenses are curved on both axes for distortion-free clarity and treated with anti-fog and POC's own Ripel coatings to keep sweat, mist, and dirt rolling right off. The vent at the top of each lens fights off fog, too, so they resist getting steamed up on warm and wet climbs. Swapping out lenses is a breeze, and an adjustable nosepiece and rubber temple inserts lock the DO Blade in place even when the going gets sweaty. You can see that the DO Blade widens at the temples, too. That's to interface seamlessly with the POC Octal helmet, although they work well with just about any brain bucket out there.
