Thank you for viewing. Children's hat, size 50cm. I often wear different hats, and I don't remember wearing this one, but I'm selling it as a used item, so please understand. It's a cap, but the back of the head has elastic. How about it for heat and sunburn protection? It will be shipped in a folded state. Instant purchase is okay. Thank you. I also sell clothes from brands like Apres les Cours and Petit main.
