Nike set-up, top and bottom set. Size is 130-140. The inside is mesh material (jacket to the elbows, pants to the knees) and the outside is a shaka-shaka material. I bought it new, but it became too small without being used. It has only been worn to check the size, and has never been used outdoors. Please understand that it has been in someone's possession before purchasing. Retail price: 9800 yen
