Helmet Size & Fit Guide
Start with your head measurement.
Use a soft tape around the widest part of your head, above your eyebrows and ears. Keep the tape level. Compare the measurement with the chart on the exact product page, then confirm fit before riding.
Read the model’s own chart
Most adult models list XS 53–54, S 55–56, M 57–58, L 59–60, XL 61–62 and 2XL 63–64 cm. FS-861 additionally lists 3XL 65–66 cm. FS-V8 starts at S and ends at 3XL.
FS-730, FS-755, FS-758, FS-X1 and FS-X1-X list L 59, XL 60 and 2XL 61 cm. These are retained exactly as printed, rather than replaced with a generic chart.
Youth sizing
FS-618kids: YS 48, YM 49–50, YL 51–52 and YXL 53–54 cm. Adult and youth size labels are not interchangeable.
A measurement is a starting point. Head shape, fit and the exact supplied version also matter. Follow the manufacturer’s fitting instructions and ask about a physical fit check if uncertain.
