The open-face HJC RPHA 31 offers enhanced shock resistance and maximum protection thanks to its Premium Integrated Matrix (PIM) Evo shell and multi-density EPS. Engineered for a quieter, more aerodynamic ride through extensive wind-tunnel testing, the RPHA 31 decreases noise level and wind turbulence. The RPHA 31 will also accept the second generation of SMART HJC Bluetooth communication systems, allowing riders to stay connected and focused on the road ahead. A full front-to-back airflow system gives superior airflow with two intake vents and four exhausts. The elongated clear anti-scratch coated visor provides 99% UV protection, is Pinlock ready (for the DKS647 Pinlock insert), and fits with HJC's quick shield ratchet system. The visor deflector decreases noise level and wind turbulence, and the visor holder reduces noise and drag forces and holds the visor tight. An adjustable 3-step inner light smoke sun shield gives optimised positioning. The interior is made from advanced anti-bacterial fabric that wicks moisture and is quick-drying for superior comfort - the crown and 3D contoured cheek pads are removable and washable, and the interior can accommodate glasses with glasses grooves for maximum comfort. The one-touch micro buckle is adjustable for the perfect fit and is ultra-secure. the HJC Rpha 31 is ECE 22.06 approved and is ready to accommodate HJC's 2ns generation of Bluetooth devices (sold seperately). Plus, this boasts HJC's 5-year manufacturer's warranty.
