Featuring complete Koroyd coverage and a Mips® rotational system, this Smith Mainline helmet provides exceptional protection; plus, internal air channels and open exhaust ports max out breathability.
Features
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
Pad kit includes 3 sets of sized cheek pads, 2 sets of sized crown liners and 2 neck rolls to ensure a proper fit̵all 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
