How to use

Place the helmet on the head so that the front edge sits just above the eyebrows, then adjust the retention system until the helmet feels snug but not tight. Fasten and adjust the chin strap so it forms a V shape under each ear and allows one or two fingers' width between strap and chin. Ensure vents remain unobstructed and check that the helmet does not shift significantly when you move your head. Replace the helmet after any significant impact or when visible damage appears.

Usage recommendations

Regularly inspect straps, buckles and padding for wear; clean the shell and liners with mild soap and water, avoiding harsh chemicals. Store the helmet in a dry place away from direct sunlight and extreme heat. Choose the S/M size for a close fit consistent with head measurements in the product sizing guidance.
