Purchased at THE NORTH FACE in Kobe Daimaru. Tech Air Sweat Hoodie. Size S, suitable for heights between 150cm and 160cm. The item was worn by a child, so please understand. It's clean with no noticeable stains. From the website: This lightweight sweat hoodie uses a special three-layer fabric that combines heat retention and breathability. The stretchy knit fabric, made from recycled materials, is formed into a three-layer structure with a cardboard-like air chamber, creating a knit fabric structure that is thick yet light, and easily generates dead air for excellent heat retention. Suitable for a wide range of uses, from training to everyday wear. The silhouette is a relaxed fit with room. It features an electrostatic care design to suppress the generation of unpleasant static electricity.
