Drop in to the trail with confidence knowing the Giro Blok MTB Goggle with Vivid Trail Lens will help you sight your lines with precision with its superior optical clarity. Utilizing a frame designed around Giro's Expansion View Technology, the Blok MTB Goggle delivers an impressively wide field of view so you can spot tricky rock gardens and off-camber corners from afar. The fit is comfortable and stable too, with a supervent foam that allows you to stay cool and focus on your lines without distraction. These goggles also feature Giro's Vivid Trail Lens, developed in partnership with ZEISS Optics specifically to handle the varying trail conditions inherent to mountain biking. The patented lens technology filters out certain distracting shades of green and orange light without taking it away completely, providing balanced color perception with the ability to see shades and contrast that would otherwise be hard to spot on dirt trails and shadowy singletrack. The overall effect is enhanced contrast and definition with less strain on your eyes, helping to improve reaction time and preserve more of your hard-earned speed.
