Helmet size guide
A helmet should feel snug all round with even pressure, here's how to find yours.
- 01Use a soft tape
A tailor's tape works best. A string and ruler is fine too.
- 02Go 2 cm above brows
Wrap around the widest part of your head, above ears and eyebrows.
- 03Measure twice
Take the largest reading and match it to the chart.
The fit test
- Cheek pads touch your cheeks firmly.
- No gap between brow pad and forehead.
- Shaking your head, the helmet moves your skin, not just slides.
- Wear it 10–15 minutes indoors; no hot spots.
| Size | Head circumference (cm) |
|---|---|
| XS | 53 – 54 |
| S | 55 – 56 |
| M | 57 – 58 |
| L | 59 – 60 |
| XL | 61 – 62 |
| XXL | 63 – 64 |
