My child wore this during club team practice. It's a size L, but it has a snug fit. Regarding the tag, I wrote their name on it, so I've cut that part off. Please be aware of this. This is a navy shirt of the Japan national team, made with Climalite material for a comfortable feel. - Brand: adidas - Color: Navy - National Flag: Japan - Emblem: Japan Football Association (JFA) - Material: Climalite Thank you for looking.
