Thank you for viewing this item. This is a 19AW fleece pants from AIE. They are very comfortable and warm. The retail price was around 30,000 yen. Made in the USA. The size is S, but the waist, length, and thigh width are large, and I think they would fit comfortably for someone who usually wears a size M. Flat measurement: Waist approximately 40cm (adjustable with the included belt) Please consider purchasing.
