How to use
Measure head circumference and position the helmet so the front edge sits approximately one to two finger-widths above the eyebrows. Use the adjustable retention system to tighten the fit until the helmet is stable but comfortable. Adjust the side straps to form a V-shape under each ear and fasten the buckle. Ensure the helmet sits level on the head and does not tilt back or forward excessively. Replace the helmet after any significant impact or if visible damage appears.

Regularly inspect the retention system, straps and padding for wear and replace components according to manufacturer guidance.
