Using the Omne Air MIPS bike helmet is easy. Just place it on your head and adjust the straps until it fits snugly. Make sure the helmet sits level on your head and covers your forehead. Before each ride, check the helmet for any signs of damage like cracks or dents. If you find any, it's time to replace the helmet. When it comes to maintenance, use a mild soap and water to clean the outer shell and the liner. Avoid using harsh chemicals as they may damage the helmet's materials. Let it air dry completely before using it again. Remember, this helmet is designed to protect you, so always wear it properly during your bike rides.
