KADOYA Ladies K'S PRODUCT Series Model: HRT4 Size: WM Uses a material jointly developed with Toray. This high-spec material boasts stretch, wind resistance, breathability, heat retention, and antibacterial/odor-control functions. The reverse side is made of microfleece material, making it warm and ideal as an inner layer for leather jackets. The product is in excellent condition, with no pilling on the fleece material and no holes or loose threads. It's easy to imagine it as a wetsuit-like cold-weather inner layer. Used only about twice and in beautiful condition. The product size is listed as S, but it is a WM (Women's Medium) size.
