Born out of years of design and research, the i31 has created the best jet helmet on the market. It starts with the next-generation visor. This new Pinlock-ready visor offers a wide, distortion-free view and now has a reinforced frame around the lower edges to reduce wind turbulence. The visor also uses the tool-free, quick-release grid system for easy installation/removal. HJC has also updated the internal sun visor with a larger coverage area than the previous model. The ventilation system maximises airflow inside the helmet, while the rear exhaust spoiler creates a vacuum effect that washes away heat. The Multi-Cool inner lining and inner cheek pad provide additional cooling properties with its moisture-wicking antibacterial fabric. The 2 Shell/3 EPS distribution reduces the weight of the helmet and offers better sizing.
