This is a reversible nylon jacket with a fleece lining, similar to L.L.Bean's Warm-up Jacket, Columbia's Loma Vista Hoodie, or Patagonia's Shelled Synchilla Jacket. I bought it at a used clothing store for about 15,000 yen. I couldn't find the product tag, so the exact product name is unknown. There's no brand tag, but I searched the washing instructions and Captain Sunshine came up. However, I don't think it's that high-end...
