Granted, the helmet is chic; wenns was going after, would keep him my daughter immediately. But with approximately 1300g it is just too hard on a four-year child's head (50 cm, XXS) because although the head is protected, however, exposed to the cervical spine in the event of the case whiplash. For back-to -the. Scooter ride too heavy for my taste. Have him sent back and replaced by another helmet (850g). The carrying my daughter without a murmur. Balaclava was with my delivery is not it?!?
