It's a set, but I think I've only worn the bottoms a few times. I'm selling it because it's too small. It's a bit thick, with a shaka-shaka material and jersey material around the lower back. Image 4: There's a stain on the butt area that looks shiny. Personally, I don't think it's very noticeable. This is a used item, so please refrain from purchasing if you are concerned about the details. #LUZeSOMBRA #Practice Pants #ASICS #NIKE #Mizuno #Soccer Junky #svolme
