This Solid N Gray model in Large uses HJC’s Premium Integrated Matrix (PIM) Evo shell, combining Carbon-Aramid Hybrid and natural fiber reinforcement materials for enhanced shock resistance, lightness, and comfort.

The integrated smoke-tinted sun visor features an anti-fog coating and a bottom-mounted operating system for quick deployment. Its multi-step adjustment allows the visor to move closer to the rider’s face for personalized shading. The included Pinlock® 120XLT® DKS467-ready HJ-39 shield provides 99% UV protection and includes an anti-scratch coating. The shield holder helps reduce noise and drag while keeping the visor securely positioned.\u003c\/p\u003e\u003cp\u003eThe RPHA Premium Fit interior uses advanced antibacterial fabric with moisture-wicking and quick-drying performance.
