HJC i10 SONAR Full Face Motorcycle Helmet.

Built to replace the CL-17, one of HJC’s best sellers, the i10 is bringing a new level of performance to the HJC lineup. The compact, modern design allows you to take to the streets in style, while still maintaining an accessible price point for the everyday rider. Improved ventilation from new intakes and exhausts increases airflow while maintenance is made easy with simple, snap-on top vents. The i10 is Bluetooth compatible with SmartHJC(Bluetooth system sold separately).

Sizing

Wrap a tape measure horizontally around your forehead. Select the helmet that is the closest fit to that size. A helmet should fit snug on your head. If it moves while wearing, it is too large. If it is painful to wear, it is too small.
