The Revolt Pro Goggles pair Giro's EXV+ frame design with a semi-spherical lens curvature, widening peripheral vision further than a standard cylindrical goggle by shaving down the rim and adding frameless zones around a larger lens. VIVID lens technology by ZEISS sharpens color and terrain definition, and a magnetic-assisted Quick Change system lets us swap between the included bright light and low light lenses without fumbling in the cold. Triple-layer face foam with a microfleece lining keeps the fit comfortable through a full day, and the OTG-friendly interior leaves enough room to wear glasses underneath without fogging. What Our Gearhead(R) Experts Are Saying:"I swapped from the bright light lens to the low light lens mid-run when clouds rolled in, and the magnets snapped it into place before I'd even stopped moving."
