RPHA 91 Carbon

The HJC RPHA 91 Carbon is a premium modular touring helmet designed for long hours in the saddle. Its carbon composite shell, compact chin bar movement, refined ventilation, and low-noise interior make it an excellent choice for commuting, road trips, and everyday touring. Performance and Comfort P.I.M. EVO Carbon shell blends carbon and carbon-glass hybrid fabric for lightweight strength and enhanced impact resistance. Dual-axis chin bar pivot keeps the chin bar close to the shell to reduce drag, wind noise, and bulk when raised. HJ-37 face shield provides a wide, clear field of view. HJ-V17 Dynamic Multi-Step sun visor is anti-fog coated and distortion-free. Advanced Channeling Ventilation System and eyebrow vents move air efficiently and support defogging. Premium fit interior uses moisture-wicking, quick-drying, anti-bacterial fabric. 3D cheek pads and an eyewear-friendly EPS design improve all-day comfort. Compatible with second generation SMART HJC Bluetooth systems, sold separately. Meets or exceeds DOT FMVSS 218 requirements. Covered by HJC's 5 year helmet warranty.
