This is an Adidas nylon jacket. The inside is a long-pile fleece, so I think it's very warm. I think it's in a clean condition with no stains. The only issue is that the letters on the Adidas logo on the left sleeve (the top of the "d" and the left side of the "s") are peeling off. I've taken several photos, so please take a look at the images. If you are at all concerned about the logo's condition, please refrain from purchasing. It has been home-cleaned. The size is marked as M, but I had my child wear it when they were wearing 150cm clothing, so I will list it as 150cm. I think it can be worn by both boys and girls. Because it's nylon, it's wind-resistant and suitable for cold weather. I think it would be good for club activities or sports.
