This is an Adidas long-sleeved T-shirt. It's likely from the late 90s to the early 2000s. I bought it at a used clothing store. The size is M. The red logo on the left chest is a key feature. There's a pinhole on the left sleeve, which is almost more than a pinhole. The hem of the sleeve is also dirty, but this is a used item, so please only purchase if you understand this. Feel free to comment if you have any questions.
