How to measure your helmet size correctly: To find the right helmet size, measure your head circumference with a flexible tape measure around the widest part of the head.
Place the tape at the front, about 1–2 cm above the eyebrows, and run it along the sides above the ears and over the largest part of the back of the head. Measure 2–3 times and compare the value in centimetres with the chart.
Important note on fit
The right helmet should fit firmly without uncomfortable pressure points. Between two sizes, most riders choose the larger one. A new helmet may feel a little tighter at first as the lining adapts.

Safe & Comfy
Every Y.10 is built with Polyfusion shell technology, known for its compactness and high impact resistance, and comes in two shell sizes for an excellent fit and comfort — the helmet stays in proportion rather than one shell being scaled across the whole range.
Enjoy the City
The wide visor gives a sense of openness inside the helmet, a feeling of freedom that is ideal for every urban condition.
Ultra-Wide Sun Visor
The integrated, lightly tinted sun visor guarantees excellent peripheral vision and protection from intense sunlight and glare. It extends and retracts manually with a fine tab on the edge of the lens.
Urban Design & Airflow
The active ventilation system allows optimal climate control inside the helmet for every situation. Some versions carry an integrated top vent with a two-stage mechanism to tune fresh-air intake to the needs of urban mobility.
Built for an Active Lifestyle
The black, breathable interior padding is fully removable so it is easy to take out and clean, and its slim shape is well thought out for riders who wear glasses.
What an Open-Face Helmet Does and Does Not Do
The Y.10 is an open-face (jet) helmet: it has no chin bar and does not protect the chin or jaw the way a full-face does. ECE 22-06 for jet helmets does not include chin protection. It is the right tool for relaxed urban and everyday riding at city speeds; for higher-speed or long-distance riding a full-face gives more protection and weather cover.
Size Guide
The Y.10 runs from XXS to XXL across two outer shell sizes (XXS–L | XL–XXL). Measure your head circumference around the widest part, about 1–2 cm above the eyebrows, and compare it with the size chart on this page. Between two sizes, most riders take the larger one.
