Using the Spark 2 MIPS helmet is easy. Just put it on your head and adjust the Ergo Fit system to get a snug and comfortable fit. For sunny days, adjust the visor to block the sun's glare. When you plan to ride for a long time, you can attach a pair of goggles. Make sure the helmet is always properly fastened before you start your ride. As for maintenance, clean the helmet regularly with a mild soap and water. Don't use harsh chemicals as they may damage the helmet. Store it in a cool, dry place away from direct sunlight. Check the helmet for any signs of damage before each use, and replace it if it has been involved in a crash or shows visible wear and tear.
