Protection
The Mainline uses full Koroyd coverage to deliver lightweight, ventilated impact protection across the entire helmet. Mips technology adds an extra layer of rotational impact management, helping reduce forces from angled crashes. It meets CPSC, CE EN 1078, NTA8776 e bike and ASTM F1952 downhill standards for maximum reassurance on demanding terrain.
Fit and Integration
Smith designed the Mainline for seamless pairing with their performance goggles. The AirEvac system channels airflow through the helmet and out through the goggles to keep lenses clear and fog free. Three cheek pad kits, two crown liners and two neck rolls allow you to fine tune the fit for stability and comfort. A traditional D ring strap ensures a secure, reliable closure.
Ventilation and Comfort
With 21 fixed vents, the Mainline maintains consistent airflow even on long, hot enduro stages. The X STATIC and Ionic+ lining helps manage odour and moisture, keeping the helmet fresh ride after ride. At just 770 g, it offers an impressive balance of strength, ventilation and low weight for all day riding.
