This is an American football game shirt made by NIKE. I bought it at a flea market in Harajuku and have stored it in a dark place. The size is US size, so it's quite large. Even at 173cm tall, it has a very baggy feel, which makes it quite impactful for 90s American hip-hop fashion. Since it's made by NIKE, it's quite rare, and when I tried it on, I think it's about a 2XL in Japanese size!
