How to use
To use the helmet, place it level on your head so that it covers your forehead without obstructing your vision. Use the adjustment dial located at the back of the helmet to tighten or loosen the internal harness until it fits snugly but comfortably. Fasten the chin strap securely, ensuring that the buckle clicks into place and the straps form a V-shape around your ears. Adjust the strap length so that there is only enough space for one or two fingers between the strap and your chin.

Measure your head circumference accurately to ensure the 55-58 cm range is appropriate
Check that the helmet sits level on your head for optimal protection
Verify that the helmet is compatible with any additional accessories you may use
Usage recommendations
Always inspect the helmet for any signs of damage, such as cracks or dents, before every ride. If the helmet has been involved in a significant impact, it must be replaced immediately, even if no damage is visible to the naked eye. Store the helmet in a cool, dry place away from direct sunlight to maintain the integrity of the materials.
