The Giro Sario Helmet and Revolt Goggle close the gap that usually opens up between a helmet's brim and a goggle's frame. Revolt's Vivid lens with Zeiss optics sharpens contrast against changing snow conditions, and the Sario's vertical tuning adjusts the helmet to sit flush against Revolt's frame and adjustable strap. What Our Gearhead® Experts Are Saying:"I swap between Revolt's two lenses from flat morning light to full sun without breaking the seal against my helmet."
