Outdoor hat (beige) purchased at Adventure World, unisex, free size. I went to Adventure World and used it then, but haven't used it since! The circumference of the hat measures 60cm! (Check the image) The seller's head circumference is 59cm and it fits perfectly! Please consider purchasing, taking into account some margin of error as this is a measurement by an amateur! ★Shipping★ Shipped via anonymous delivery. * It will be folded for shipping. Thank you for your understanding. ★Product Description★ With a chin strap. Wire (probably) is inserted in the brim of the hat, allowing you to shape the hat! (Check image 6)
