Product Details
HJC RPHA 12 Kate MC28 Blue / Purple / White
The HJC RPHA 12 Kate MC28 Blue / Purple / White is a premium sport helmet for road and track riding, combining lightweight construction with an aerodynamic shape and a wide field of view. Its contoured fit and practical comfort features help you stay focused on the ride.
Shell construction and comfort
The P.I.M. EVO shell combines Carbon-Aramid hybrid and natural fibres for lightweight, shock-resistant performance. Antibacterial interior fabric wicks away moisture and dries quickly, and the crown and cheek pads can be removed for washing.
Ventilation and visibility
The ACS Advanced Channelling Ventilation System uses four intakes and three exhausts to move warm air out of the helmet. Side exhaust vents help remove exhaled air and reduce wind noise. The HJ-42 visor has a two-way pivot mechanism for smooth operation and improved sealing, while the enlarged eye port supports peripheral vision.
