Description

Featuring complete Koroyd coverage and a Mips® rotational system, the Smith Mainline helmet provides exceptional protection; plus, internal air channels and open exhaust ports maximize 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
• Unique pad kit includes 3 sets of sized cheekpads, 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
• Camera- and light-mount compatible
• Downhill certification: ASTM F1952
• Certification: CPSC, CE EN 1078
