This is a GIRO helmet. It has ventilation holes for comfort. Size: M (55.5-59cm) I am selling this on behalf of a family member. A name sticker is attached to the black painted part. It's a white sticker, so it's not very noticeable. They said they remember buying it for around 20,000 yen at the time. There are some minor scratches, but it's still usable. I will include a bag, although it's from a different manufacturer. Please refrain from purchasing if you are sensitive to used items. Please consider purchasing only if you understand that this is a used item stored at home and inspected by an amateur. - Brand: GIRO - Color: White/Green - Design: Stripe pattern - Ventilation holes: Yes Thank you for looking.
