Using your Lazer Lupo Kineticore MTB helmet is a breeze. First, put the helmet on your head. Use the Lazer TurnSys system's dial to adjust the fit until it's snug but not too tight. You can easily do this even when you're on the move. If you wear sunglasses, the special shape of the helmet will keep you comfortable. For better visibility at night or in low - light conditions, attach the Universal Lazer LED at the rear using the Direct Mount. When the weather gets cold, add the Winter Kit to stay warm. Here are some things to keep in mind. Make sure the helmet fits well before you start riding. Check the straps regularly to ensure they're in good condition. Don't use the helmet if it has been in a serious impact. To maintain your helmet, clean it with a mild soap and water. Avoid using harsh chemicals. Let it air - dry naturally. Store it in a cool, dry place away from direct sunlight. With proper use and care, your Lazer Lupo Kineticore helmet will serve you well for many rides.
