This Small-size helmet features HJC’s PIM EVO shell, constructed from a blend of carbon-aramid fiber, carbon fiber, glass fiber, organic non-woven fabric, and natural linen fiber. The composite shell helps provide enhanced shock resistance while maintaining a lightweight, comfortable construction for extended motorcycle rides.\u003c\/p\u003e\u003cp\u003eThe HJ-37 visor is Pinlock® 120XLT® prepared, anti-scratch coated, and provides 99% UV protection. An integrated smoke-tinted sun shield uses a dynamic multi-step mechanism for quick, convenient operation and anti-fog clarity. The sun shield can be positioned closer to the rider’s face for personalized shading. Eyebrow ventilation channels air toward the visor area to support defogging and airflow, while the dual-axis chin-bar mechanism keeps the bar close to the shell to help reduce wind resistance and noise. The chin bar retracts in the open position for easier helmet installation.\u003c\/p\u003e\u003cp\u003eInside, the RPHA Premium Fit interior uses antibacterial, moisture-wicking, quick-drying fabric for all-day comfort.

The crown and cheek pads are removable and washable for convenient maintenance. This helmet is compatible with the second-generation Smart HJC communication system, which is co-developed with SENA and designed for seamless integration with the RPHA 71, RPHA 91, RPHA 31, and i71 models.
