How to use

Measure head circumference at the widest part of the head and select the medium size for measurements within 54–58 cm. Place the helmet on the head so the front rim sits just above the eyebrows and adjust the retention system until the helmet is stable but not tight. Fasten and adjust the chin strap to a comfortable position that prevents excessive movement; the strap should be snug under the chin without restricting breathing.

Replace the helmet according to manufacturer guidance after a major impact or when padding and fit are compromised.
