Using this Lazer Lupo Kineticore MTB helmet is easy. First, adjust the Lazer TurnSys system to fit your head comfortably. Make sure it's not too tight or too loose. When you're out on the trail, the integrated visor can block the sun or debris. If you're riding at night, you can attach Lazer LED lights for better visibility. In winter, use the winter kit for extra warmth. As for maintenance, clean it regularly with mild soap and water. Don't use harsh chemicals as they might damage the helmet. Check for any signs of wear and tear, like cracks or loose parts, and replace the helmet if needed.
