This is an adidas track jacket. The listed size is Japanese L. The seller often chooses L at Uniqlo, but feels this fits snugly but is still a wearable size. It is a used item, and detailed information such as the year of manufacture is unknown. There are some slight snag marks (see image). The quality tag is missing, but it is likely made of adidas's typical polyester tricot fabric. For price negotiations, please provide your desired price for a smoother transaction! - Brand: adidas - Size: L
