Size S, approximately 52cm (official measurement) I believe it's in good condition with little wear. It's originally thin, but the lining is mesh fabric, providing good breathability. The neck sunshade can be stored, and can be tucked inside the hat when not needed. Chin strap included. The tag has a name written on it, which has been blacked out. Will be folded for shipping. Shipping method may switch between Yu-Yu and Raku-Raku. Please understand that this item has been stored at home.
