Its aerodynamic shape improves stability at high speeds, while a large upper air intake ensures optimal ventilation for rider comfort. The helmet comes equipped with a clear anti-scratch shield, a Pinlock 70 MaxVision insert for a wide, fog-free field of view, and an integrated drop-down sunshield for convenient glare protection in bright conditions. This model also features colored vents and shields that accent the helmet’s graphics. The light smoke and transparent iridium shields are DOT-approved for nighttime riding, meaning they can be shipped pre-installed.

How to measure
Measure the circumference of your head with a tape measure, starting above the ear, circling completely around about half an inch above the eyebrows and across the fullest part of the back of the head. Measure several times for accuracy. If you fall between two sizes, choose the larger; the helmet should be as snug as possible without causing pain.
