This is a Nike running wear set, top and bottom. Both are made of thin, lightweight knit material that fits the body snugly. Although there is a difference in wear between the top and bottom, both are still in good condition and can be used. It's a bit cheaper than the retail price, so please consider purchasing it. ▽Shirt▽ M size Pacer series With thumbholes.
