Smith, Mainline MIPS

The pinnacle helmet in Smith's mountain bike collection is the all new, DH certified, Mainline. Featuring complete Koroyd® coverage and the MIPS® rotational system, the Mainline provides exceptional protection while combining internal air channels and open exhaust ports to maximize breathability. As goggle fit and ventilation are crucial for grueling days, the AirEvac™ system relieves hot air that builds up on your goggles, to prevent fogging. Included with the Mainline are three sets of uniquely sized cheekpads, two sets of uniquely sized crown liners, and two unique neck rolls to ensure a proper fit; all components can easily be removed for cleaning. Ride with confidence knowing the Mainline is secured with a tried and true D-ring chin strap fastener.
