KASK Helmet Size Guide
How to measure my size?
Helmet sizes are based on head circumference. Measure your size by wrapping a measuring tape snugly around the widest possible circumference - from the most prominent part of the forehead (often 1-2 fingers above the eyebrow) around to the widest part of the back of your head. Measure 3 times, and take the largest number. Using the chart above, select your size.
