These are the popular Nike Challenger running shorts (retail price: 5,280 yen). They are size S, and although it's difficult to tell from the photos, the color is a beautiful denim turquoise blue (see photo 1). Below is the product description: The iconic Nike Challenger shorts feature brand new, more supportive briefs and comfortable woven fabric. With mesh details and pockets to securely store small items, these versatile shorts are perfect for everyday wear. This product is made with at least 75% recycled polyester fibers. These are new, purchased directly from a Nike store. I'm also selling various other items! Please check them out.
