How to use: When you're on the more technical parts of the trail, use the full - face mode for extra protection. Just press the magnetic chinbar to switch to open - face mode when you want more ventilation or a different riding style. Note: Always make sure the chinbar is properly locked in full - face mode. Check the magnetic connection regularly for any signs of wear. Maintenance: Clean your helmet with a mild soap and water. Don't use harsh chemicals as they can damage the helmet. Store it in a cool, dry place away from direct sunlight to keep it in good condition.
