Using your Lazer Finch Kineticore helmet is a breeze. First, put it on your head and adjust the fit using the Lazer TurnSys system. Just give the dial a simple turn until you feel a snug and comfortable fit. When you're out on the trails, the well - placed vents will keep your head cool, and the visor will protect your eyes from the sun. If you wear sunglasses, the special recesses in the helmet will make sure they fit comfortably. For added safety, you can attach the Universal Lazer LED at the rear. In colder weather, install the Winter Kit to stay warm. Here are some things to keep in mind. Always make sure the helmet fits properly; an ill - fitting helmet won't protect you well. Don't expose the helmet to extreme heat or chemicals as it can damage the materials. To maintain your helmet, clean it regularly with a mild soap and water. Gently wipe it down, and let it air dry. Check the straps and the TurnSys system periodically for any signs of wear and tear. If you have any concerns about the helmet's condition, it's best to replace it to ensure your safety.
