I purchased this on Mercari a little while ago. The following is the description from the time of purchase: UA Knit Tracksuit Girls Product Number: 1363380-002 Size: YMD (140cm) Retail Price: 6600 yen Main Material: 100% Polyester Material Composition: 79% Polyester, 21% Polyurethane Top (Sleeve Length: 72cm, Body Width: 39.5cm, Length: 49.5cm) Pants (Waist: 62cm, Rise: 24.5cm, Thigh Width: 26.5cm, Inseam: 64.5cm, Hem Width: 11.5cm) - Mesh material is used in the switching parts for enhanced breathability. - Soft and comfortable to wear, and warm, thanks to the brushed tricot knit material. - The quick-drying material quickly wicks away sweat. - Jacket: With pockets - Ribbed cuffs and hem - Jacket: Loose fit and drop shoulders provide a comfortable fit. - Pants: Ribbed waistband with a drawcord on the outside, with pockets. Tapered fit with a gathered hem. ※ In my opinion, although it's size 140cm, I felt it was a little small. I wore it about 4-5 times a month for soccer class. There are no noticeable scratches or stains, and no shine on the knees.
