Perfect for standard intermediate head profiles.

Narrow chin bar; best for oval head shapes; requires precise sizing due to limited adjustability.

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 Complex Laminate Construction (CLC) with PB-SNC2 peripheral belt reinforcement and R75 smooth shell geometry for glance-off impact energy redirection paired with VAS (Variable Axis System) shield mechanism with dual-latch shield lock and IC Duct 5 ventilation intake ports. The interior utilizes One-piece multi-density EPS liner with Eco-Pure anti-microbial removable Dry-Cool interior lining with pre-shaped speaker cutouts for seamless Bluetooth comms integration.

The Corsair-X Nakagami 3 is engineered as a high-integrity Track/Race protective system, utilizing a structural shell constructed from PB-SNC2. 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, Snell M2020, 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.
