Kids Cap - New Era Color: Black Youth Size (Approximate: 6-15 years old, height 130-160cm) I recently purchased this new and wore it once, but my child doesn't seem to like it, so I'm selling it. The tag has been removed. 9TWENTY The [9TWENTY] is characterized by its light fit. It's a silhouette that's easy to wear for both men and women. ・About Size The size can be adjusted with the rear adjuster (approximately 52cm to 55.8cm).
