Using the Smith Dispatch Bike Helmet is a breeze. First, put on the helmet and use the VaporFit system. Just turn the dial to get the perfect fit for your head. When you're riding, especially at night or in low - light areas, make sure the rear LED light is turned on. You can recharge it easily when the battery runs low. The Fidlock strap buckle is great for quick one - hand operation. When you're in a hurry to put on or take off the helmet, use this feature. As for maintenance, keep it clean. You can use a mild soap and water to wipe the outside and the padding. Don't expose it to extreme heat or direct sunlight for a long time as it may damage the materials. And always check for any signs of wear and tear before each ride. If you notice any cracks or damage, it's time to get a new helmet.
