Under Armour's fleece-lined, "shaka-shaka" (windbreaker-like) top and bottom set. It's also stretchy, making it very easy to move in. For the coming season, it can be used for various purposes such as running, futsal, and one-mile wear, and I think it will be very useful. The design is not flashy, so I think it can be used regardless of age. It's in relatively good condition, having been worn only once. The size is probably around L. It fits perfectly on someone 171cm tall. Thank you.
