I apologize that the photos aren't very flattering. I purchased this at the Prada Sport (authorized store) near Miyashita Park in Harajuku about 20 years ago. There is no lining. It's simple but very practical. I think it can be used for sports (gym, running, etc.). Excellent condition. Please check the photos. I can attach other photos if you request them (e.g., seams). I'm very sorry that the photos aren't very good. I've heard that many items with questionable authenticity are listed on Mercari, but this item is undoubtedly genuine. Of course, you are welcome to have it authenticated. You can check the details, and I will take photos of any areas you request, so please feel free to ask. Please refer to the measurements below for the size. It's "Tg50," but it should fit anyone who wears M to L. There is no sign of wear on the exterior. [Measurements by a non-professional] Shoulder width: 40 cm Body width: 48 cm Length: 55 cm (from the back of the neck to the hem) Body length: 60 cm Sleeve length: 60 cm The armpits are open from the beginning. It's not torn. * There is a fray of about 2 mm on the right hem (photo attached). I will respond and ship quickly. This is a high-value item. To prevent any trouble, please ask any questions "before purchasing." Color: Black Material: Nylon Stains, tears, odors, etc.: None
