Size Chart For Helmet
How to measure the size of your head
First, measure the circumference of your head with a measuring tape.
Measure from the highest point of your forehead, just above your eyebrows, horizontally backwards to the highest point of the back of your head and around.
Based on the measurement, choose the size from the table below.
However, unlike hats, helmets cannot be sized by head circumference alone.
Also, helmets of the same manufacturer may feel different even if they are the same size depending on the model.

Ordering Size | XS | S | M | L | XL | 2XL |
Head Measurement (cm) | 53 - 54 cm | 55 - 56 cm | 57 - 58 cm | 59 - 60 cm | 61 - 62 cm | 63 - 64 cm |
