The Smith Mainline MIPS Full Face Mountain Bike Helmet is Smith's premier downhill-certified helmet, engineered for riders who demand uncompromising protection on the most technical terrain. Whether you're racing enduro, charging steep descents, or spending long days at Whistler Bike Park, the Mainline delivers lightweight comfort, exceptional ventilation, and confidence-inspiring safety.
Built with complete KOROYD® coverage and the Mips® Brain Protection System, the Mainline helps absorb impact energy while reducing rotational forces during angled impacts. Downhill certified to ASTM F1952, it also meets CPSC, CE EN1078, and NTA8776 E-bike standards, making it one of the most capable full-face helmets available. The AirEvac™ ventilation system integrates seamlessly with Smith goggles to minimize fogging, while 21 vents maximize airflow on long climbs and demanding descents. Multiple cheek pads, crown liners, and neck rolls allow for a fully customizable fit, ensuring comfort through every lap.
