A reversible hat with a check pattern based on blue, red, and yellow, and light blue. The size is not indicated, but my child with a large head was able to wear it until they were 2 years old. I think it can be worn up to about 50cm. The material is cotton. There are no noticeable stains or fuzziness, and it doesn't wrinkle easily even when folded, making it convenient to carry around. It can be used regardless of gender. It is stored personally. Please understand.
