It had a detachable chin strap, but I lost it. It has fabric attached to prevent sunburn on the neck, which can be tied into a ribbon shape when not in use. It can be worn reversibly. Size: 56cm *Please note that these are amateur measurements, so there may be some errors. I washed it at home and stored it at home for several years. There were no noticeable scratches or stains, but there is some slight fuzzing. There may be individual differences in how it feels, and I may have overlooked something, so please understand that this is a used item worn by a child, and we ask for your understanding. Please be aware that it will be shipped folded.
