GUIDE

Find the perfect size for your ROOF helmet in just a few seconds.

Designed for your
safety & comfort

Optimal safety

A firm, even fit guarantees maximum protection in the event of an impact.

Long-lasting comfort

The right size reduces fatigue, even on long rides.

Stability & noise reduction

A well-fitted helmet stays stable at high speed and effectively filters out noise.

Step by step

📏

Use a flexible tape measure to go around your head. If you don't have one, a piece of string or a shoelace will do.

📐

Position it 2 cm above your eyebrows, passing above the ears and around the back of the skull.

✍️

Note the measurement in centimetres: that is your exact head circumference.

👉 If your head circumference is greater than 56.5 cm, choose size SM (57).

Frequently asked questions

Choosing the right helmet size is essential to ensure comfort and safety. If you are between two sizes, here are our recommendations:

Prioritise fit: a helmet should be snug without any painful pressure points.
Test movement: it should not shift when you shake your head, nor compress excessively.

👉 Tip: when in doubt, always go up to the larger size.

Our new ranges feature an innovative adjustable cheek pad and liner system for truly personalised comfort:

Customisable liner: additional pads to increase or reduce volume. Available on the Desmo 3 Carbon, Wisper, Roadster, Boxxer, Boxxer 2 and Carbon.
Customisable cheek pads: various thicknesses available as accessories on this website and at our dealers. Available on all models.
