Thank you for viewing. These are Tabio knee-length leggings. The fabric is an inner layer with a moderate thickness, making it less likely to show through outerwear. The size is marked M-L, but the fit is equivalent to S-M. Therefore, I have categorized it as S. 80% cotton, 15% nylon, 5% polyurethane Color: Gray系 (Gray-ish) Size: S
