Featuring complete Koroyd coverage and a Mips® rotational system, the Smith Mainline helmet offers exceptional protection while the internal air channels and open exhaust ports maximize breathability.
- With 21 optimized vents, the AirEvac ventilation system allows goggles and helmet to function as a system, venting warm, moist air away from the goggles—and away from the head
- Koroyd provides superior impact absorption, design flexibility and ventilation when compared to materials traditionally used in helmet construction
- Utilizing crumple-zone cylinders that crush uniformly on impact, Koroyd manages energy more efficiently with less volume than traditional protection materials
- Rotational motion can cause brain injuries; with Mips, a low-friction layer slides 10 to 15 mm in all directions, reducing rotational motion to the brain during impact
- Unique pad kit includes 3 sets of sized cheekpads, 2 sets of sized crown liners and 2 neck rolls to ensure a proper fit—all of which can easily be removed for cleaning
- Pads are made from Hybrid X-Static/XT2 for antibacterial performance
- Ride with confidence, knowing the Mainline is secured with a tried-and-true D-ring chin strap fastener
- Lightweight Aerocore in-mold construction
- Adjustable visor
- Camera- and light-mount compatible
- Downhill certification: ASTM F1952
- Certification: CPSC, CE EN 1078
- E-Bike helmet certification: NTA-8776
