HJC i20 Solid Open Face Motorcycle Helmet.

The all-new HJC i20 is designed to give riders a different approach to the classic open-face/half helmet. This street fighter-inspired helmet comes with a removable mask and wide-vision anti-fog coated sun visors (Smoke & Clear) that manually operates with pull tabs located on each side of the helmet. The Advanced Polycarbonate Composite Shell is lightweight and offers a superior fit, using a 3-shell breakdown from sizes XS up to 2XL. This helmet is also ready to accept the SMART HJC Bluetooth systems (10B and 20B).

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.
