Children's junior helmet GIRO Dime FS, size S 51–55 cm, black

GIRO Dime FS is a junior children's cycling helmet in size S (51–55 cm) with a black finish. It combines a lightweight shell, internal comfort padding and multiple vents to provide head protection for everyday cycling, commuting and recreational rides. The helmet includes an adjustable fit system that secures the helmet on smaller heads and helps maintain stability during movement while promoting airflow and comfort for young riders.

Advantages

The helmet's lightweight construction reduces neck strain on young cyclists while the adjustable fit system allows for precise sizing within the 51–55 cm range. Internal padding increases comfort on longer rides and can be repositioned or removed for cleaning. Multiple ventilation openings improve airflow to help regulate temperature during activity. The simple strap adjustment and buckle design enable quick fitting and safe retention.

How to use

Place the helmet on the child's head so it sits level and covers the forehead without tilting backward. Adjust the retention dial or mechanism until the helmet feels snug but comfortable; it should not move excessively when the child shakes their head. Fasten and adjust the chin straps so they form a V-shape under the ears and the buckle closes securely; the strap should allow one or two fingers' space under the chin. Periodically check fit and pad condition, and clean or replace pads according to manufacturer guidance to maintain hygiene and fit.

Usage recommendations

Ensure the helmet size matches the child's head measurement (51–55 cm). Replace the helmet after any significant impact, visible damage or once pads and fit no longer provide a secure fit. Store the helmet away from direct sunlight and high heat to preserve materials and performance.
