This is a short-sleeved T-shirt from Adidas men's sportswear. Please refer to the tag on the neck for the size. I believe it's probably a Medium, but it's difficult to tell, so please use the flat measurements as a reference. Measurements are approximate due to being done by hand, so please understand. Shoulder width: 45 cm Sleeve length: 21 cm Body length: 66 cm Body width: 50 cm The area around the shoulder blades on the back and the sides are mesh. This would be a good shirt for the summer. I've worn it a few times, but I can't remember how many. However, I haven't worn it in a long time and have stored it in a dark place after washing. I think it's in good condition, but there are individual differences, so please understand that it is used clothing. If you are sensitive to this or are looking for a perfect item, please refrain from purchasing. Thank you for your consideration.
