The Smith Mainline MIPS Helmet is a downhill-certified full-face helmet built for enduro, downhill and high-speed trail riding. It combines complete KOROYD coverage, Mips impact protection and Smith goggle integration to support safety, airflow and clear vision on demanding rides. Multiple pad sets, washable liners and a D-ring chin strap help create a secure, tuned fit.Key Features and Benefits:Complete KOROYD coverage: KOROYD uses welded tubes that crush on impact to absorb energy while still allowing air to move through the helmet. This gives the helmet lightweight impact protection with added ventilation, so it can protect without feeling heavy or closed in.Mips Brain Protection System: Mips is designed to reduce rotational forces from angled impacts to the head. This adds an extra layer of protection inside the helmet, helping manage impacts that can occur during fast or technical riding.Downhill-certified protection: The helmet meets U.S. CPSC, CE EN 1078, NTA8776 E-Bike and ASTM F1952 Downhill standards. These certifications show it is built for high-impact riding, giving riders a helmet suited to enduro stages, bike parks and downhill use.Smith goggle integration: The helmet is shaped to work with Smith performance goggles for comfort, venting and secure storage. This helps reduce pressure points, supports stable goggle placement and keeps the rider's setup clean and practical.AirEvac ventilation with 21 fixed vents: The AirEvac system works with Smith goggles to move warm air away from the lenses. Paired with 21 fixed vents, it helps manage heat and reduce fog, so vision stays clear during hard efforts and long descents.Custom fit pad system: Three washable cheek pad kits, two crown liners and two neck rolls allow the fit to be fine-tuned. The D-ring chin strap fastener then helps hold the helmet firmly in place, giving a secure feel on rough ground.The Smith Mainline MIPS Helmet is made for riders who need strong protection without losing comfort, airflow or goggle performance. Its full-face design gives wide coverage, while the adjustable visor, anti-bacterial lining and 770g weight help keep it practical for race days, uplift laps and enduro riding.Choose the Smith Mainline MIPS Helmet for certified full-face protection, stable fit and clean goggle integration in one lightweight downhill-ready package.
