This is a child's helmet purchased a few years ago from Asahi Cycle. I'm selling it because my child outgrew it without using it much. It's light and cute, so please use it. This is a kid's in-mold helmet for bicycles developed by REV SPORTS, a helmet brand from America. It has the same structure as a typical adult helmet, with the impact-absorbing foam and outer shell integrated, providing excellent impact resistance and durability. It is also a helmet that has obtained the SG mark, the safety standard in Japan.
