This is a North Face down jacket. The size is Youth M (10-12), which I believe is around 150cm in Japanese sizing. It was purchased from an authorized retailer in the US. This model is not sold in Japan and has high functionality that rivals adult models! (Please check the images for details) My child doesn't like wearing down jackets much, so it has hardly been worn and is in excellent condition. It is a genuine product, but it has been worn a few times by my child, so please only purchase if you understand this.
