Size Guide

Measure around your head about 2.5 cm above your eyebrows and ears, keeping the tape level. Use the resulting measurement in centimetres to find your size below. If you fall between two sizes, take the larger — the dial system adjusts down for a precise fit.

A correctly fitted helmet sits level, covers the forehead, and does not move when you shake your head with the harness undone. If you are unsure, have the fit checked in person before riding.
