Size: 12-24M Outdoor, Swim Bucket Hat This hat is perfect for leisure activities. I used it for my child's pool time, but there are no stains as they didn't play in the mud! It may have faded slightly from the original color due to multiple washes. It's made of a lightweight material, and the neck loop is easy to remove, making it stress-free for children, and they wore it often. This size is suitable for children in nursery school or kindergarten.
