The HJC RPHA 31 Dereen MC5SF XL helmet combines advanced safety features with aerodynamic design for a superior riding experience. Crafted with the Premium Integrated Matrix (PIM) Evo shell and multi-density EPS foam, this helmet offers enhanced shock resistance and lightweight comfort. Its meticulously engineered shell reduces air resistance and provides stability at high speeds, making it ideal for both city commuting and long-distance touring.

Equipped with a dynamic multi-step sun visor, the RPHA 31 allows quick deployment via a bottom-positioned mechanism, providing excellent glare reduction and anti-fog clarity. The smoke-tinted visor is anti-scratch coated and offers 99% UV protection, ensuring durability and pristine visibility. The visor’s multi-step adjustment feature lets riders position it up to 10 mm closer to the face for personalized shading and comfort. Additionally, the integrated sun visor mechanism reduces noise and turbulence, contributing to a quieter, more stable ride.
The helmet features the latest P.I.M EVO construction, incorporating Carbon-Aramid Hybrid and Natural Fiber reinforcements that enhance shock absorption while maintaining a lightweight profile. The interior is lined with advanced anti-bacterial, moisture-wicking fabric, and the crown and cheek pads are removable and washable, allowing a customizable fit. The helmet’s extended shell and chin EPS provide full face-level protection, aligning with modern safety standards. Designed with rider convenience in mind, the RPHA 31 supports the second-generation SMART HJC Bluetooth communication systems (sold separately), ensuring seamless connectivity without distraction.
