This is a Nishimatsuya nylon jacket. It uses two colors: navy and blue. Size 80. The crinkly fabric makes it very versatile. It's useful from spring to autumn. It's also good for when it gets a little chilly from air conditioning in the summer, and since it's water-resistant and light, it's easy to carry around. It has some signs of use, but I don't think there are any noticeable stains.
