Using your Lazer Strada KC Helmet is easy. First, adjust the ScrollSys system to fit your head snugly for maximum comfort. Put on the helmet and make sure it sits level on your head. The eyewear grippers are handy for keeping your sunglasses or goggles in place when not in use. You can also attach a rear light to the docking area for better visibility. When it comes to maintenance, use a mild soap and water to clean the helmet regularly. Avoid using harsh chemicals as they may damage the material. Store it in a cool, dry place away from direct sunlight. Remember, always check the helmet for any signs of damage before each ride. If it has been involved in an impact, replace it immediately for your safety.
