Using your Fox Speedframe Pro MIPS Helmet is easy. First, adjust the 360 - degree fit system to get a comfortable and secure fit on your head. Then, fasten the Fidlock® SNAP helmet buckle. You can adjust the multi - position visor according to the sunlight or your riding posture. When riding, make sure the helmet is worn properly at all times. For maintenance, avoid exposing the helmet to aerosol sprays like bug repellent and sunscreen as they can damage the finish. You can clean the XT2® antimicrobial comfort liner with mild soap and water. If you notice any signs of damage to the helmet, like cracks or a loose fit, it's time to replace it.
