Adidas inner shirt. This is an inner shirt that fits closely to the skin, like spats. The size has faded, but it's probably a Japanese size M. It fit perfectly for someone 172cm tall and 65kg. I bought and wore it for soccer, but I think it can also be worn for running, etc. This is a used item, so please purchase only if you understand this. Please note that we do not accept returns. Thank you.
