Using your Krash Pro ABS helmet is easy. First, adjust the fit system to make sure the helmet sits comfortably on your head. Make sure it's not too tight or too loose. When you're riding, always fasten the chin strap securely. Remember, this helmet is for kids and youths, so don't let adults use it. After each use, wipe it down with a soft, damp cloth to keep it clean. Store it in a cool, dry place away from direct sunlight. Check the helmet regularly for any signs of damage like cracks or dents. If you notice any, it's time to get a new one.
