I purchased this jacket at a used clothing store a few years ago and have worn it several times. It's a FILA velour track jacket, not released in Japan. It's a US size S, which fits like a Japanese size M. The color is NAVY x RED. The ribbing is slightly stretched, but it doesn't affect wearability. Please check the photos for the condition and only purchase if you understand. Regarding the size: Length: Approximately 60cm Sleeve length: Approximately 70cm (measured from the neckline) Width: Approximately 48cm (flat measurement) Shoulder width: Approximately 40cm (flat measurement) Please note that these are amateur measurements, so there may be slight variations. To prevent product substitution, returns and exchanges are not accepted. Thank you for your understanding.
