This is an UNDER ARMOUR youth-sized cap. It's a size that should fit children aged 4-11 years old. The cap has been used by a child, so there is some fuzzing on the logo and deterioration of the inner elastic. I bought this in the US, so I think the color is not very common in Japan! Please check the condition in the images and only purchase if you are satisfied with the used condition. Under Armour UNDER ARMOUR Cap Youth youth Kids
