Thank you for viewing. This is a new, unused item purchased from a Millet shop and stored without being used. It's a foreign XS size (Japanese S size). It's a windbreaker, I believe, but the lining is mesh, providing better comfort and warmth than a single-layer shell jacket. It's suitable for mountain climbing and camping, and the understated navy color with a discreet logo makes it a great choice for everyday wear. - Brand: MILLET - Material: Nylon, Polyester - Features: Lightweight, compact, durable water repellency - Size: Japanese S (Foreign XS) Model number: MIV01982 Manufacturer's recommended size: Height: 150-160 cm Bust: 72-80 cm I will pack it compactly and ship it. Shipping may take longer depending on weather conditions. Thank you for your understanding.
