Perfect for standard intermediate head profiles.

Designed for adventure riding with a slightly extended rear profile; fits most head shapes but may feel tight on very large skulls due to the dual-sport visor mechanism.

How to measure

Wrap a cloth measuring tape around your head just above your eyebrows and ears. Pull the tape comfortably snug, read the length, and repeat for consistency.

Engineering & Biomechanical Safety Analysis

Features 3K Carbon Fiber shell featuring Flex Impact Liner with progressive three-layer density rotational energy management paired with Panovision Class-1 optics visor with extended lateral field of view. The interior utilizes Virus CoolJade anti-bacterial lining paired with Magnefusion magnetic removable cheek pads with pre-shaped speaker cutouts for seamless Bluetooth comms integration.

The MX-9 Adventure MIPS Stripe TC-5 is engineered as a high-integrity Adventure/Dual Sport protective system, utilizing a structural shell constructed from Polycarbonate. This structural layup is engineered to provide progressive kinetic energy dissipation during impact deceleration, distributing localized shock across outer lamina layers while minimizing deformation transfer into the internal multi-density EPS liner.

Certified to DOT, ECE 22.05 protocols, the architecture is subjected to rigorous linear deceleration limits and oblique impact evaluations to mitigate rotational acceleration forces associated with diffuse axonal injury. For a deeper breakdown of rotational thresholds and impact testing speeds, consult our ECE 22.06 vs DOT vs SNELL engineering benchmark.

Internal geometry follows a Intermediate Oval cranial profile, designed to mitigate focal pressure hot spots across the parietal ridges while maintaining uniform radial clamping pressure along the zygomatic arch. Riders seeking optimal retention stability and break-in guidance should review the cranial aspect ratios and head shape guide as well as our 3D cheek pad density protocol.

Shell composite integrity and acoustic sealing are further optimized through channelized EPS porting and aerodynamic laminar profiling. To learn how shell composites resist stress cracking under prolonged environmental cycling, inspect the composite material comparative matrix.
