HJC RPHA 70 ST Carbon Helmet
The RPHA lineup just got even more bad-ass than it already is, now available in carbon fiber. HJC’s newly launched carbon helmets include the RPHA 11, RPHA 70 ST and RPHA 90S. While there is no question that the carbon finish is visually appealing, it is also even lighter than HJC’s lightweight PIM+ shell material. Carbon fiber creates a flexible, yet durable structure for enhanced shock absorption.
Features:
- Advanced P.I.M. Plus (Premium Integrated Matrix Plus) construction: carbon fiber and carbon-glass hybrid fabric for enhanced shock resistance
- Intake and exhaust top vents for maximum air circulation
- Rear vent switch for easy control of air flow
- Anti-fog HJ-1L smoke tinted sunshield deploys quickly
- RapidFire shield replacement system: quick, tool-less shield removal and installation
- Emergency cheek pads removal
- Multicool interior with advanced anti-bacteria fabric provides enhanced moisture wicking and quick drying
- Crown and cheek pads are removable and washable
