Smith Mainline Full Face Helmet – Enduro & Downhill MTB
Built for aggressive riding on Whistler’s bike park trails and alpine enduro lines, the Smith Mainline is a downhill-certified full face helmet designed for speed, airflow, and confidence. Lightweight KOROYD® coverage and Mips® technology work together to absorb impact energy and reduce rotational forces when things get rowdy.
With 21 fixed vents and Smith’s AirEvac™ ventilation, the Mainline pairs seamlessly with bike goggles for cool, fog-free vision on long descents. Multiple cheek pads, liners, and neck rolls let you dial in a secure, custom fit—whether you’re racing enduro or lapping the park.
