Using your Giro Agilis MIPS Women's Helmet is easy. First, adjust the Roc Loc 5.5 MIPS system to fit your head comfortably and securely. Make sure it sits level on your head. When riding, always fasten the chin strap tightly. As for maintenance, use a mild soap and water to clean the helmet regularly. Don't use harsh chemicals as they can damage the helmet's materials. Store your helmet in a cool, dry place away from direct sunlight. Check the helmet for any signs of damage like cracks or dents before each use. If you're involved in an accident, replace the helmet immediately, even if there are no visible signs of damage.
