Oakley sweatpants. Regarding the size, it says S in the 6th image, but it's a Japanese size M. Made of sturdy sweat fabric, so you can wear them regardless of the season. They are in relatively good condition, but there is a slight scratch on the hip area. Please understand that these are used items that a child has worn. The scent of fabric softener remains, so please refrain from purchasing if you dislike fragrances. If you have any other questions, please comment.
