ENGINEERED ABSORPTION
Koroyd's unique thermal welding process creates a structure that excels in energy absorption. Upon impact, its cores crush in a controlled manner, effectively decelerating the energy and minimizing trauma levels.

ENGINEERED PROTECTION
The helmet features thousands of co-polymer extruded tubes, thermally fused to form a core that offers unparalleled consistency and engineering precision. Each Koroyd segment adheres to strict specifications for durometer, size, and thickness, ensuring maximum impact resistance and a visually appealing finish.

FULL BREATHABILITY
Koroyd doesn't only provide intense energy absorption; it also maintains breathability without sacrificing impact performance. Its open-cell construction invites cool air in while expelling warm air from the rider's head. This design, integrated with internal channels, forms the complete Aerocore structure, ensuring ventilated protection.

The Smith Mainline helmet stands out as the pinnacle of enduro bike helmets, featuring essential safety innovations that empower you to tackle the trails with assertiveness. Regardless of whether you’re competing or casually riding, you can rely on its lightweight and breathable design that fits perfectly with your goggles.
