Using your Giro Agilis MIPS road helmet is easy. First, make sure it's the right size for you. The helmet is designed for medium head sizes between 55–59 cm. Put it on your head and adjust the Roc Loc 5.5 MIPS fit system until it feels secure and comfortable. You should be able to shake your head without the helmet moving around. When you're riding, the 32 wind tunnel vents will keep your head cool. As for maintenance, use a mild soap and water to clean the helmet. Don't use harsh chemicals as they may damage the shell or the liner. After cleaning, let it air - dry. Also, inspect the helmet regularly for any signs of damage, like cracks or dents. If you notice any, it's time to replace the helmet to ensure your safety on the road.
