Kids' windbreaker. Purchased on Amazon. It has elastic cuffs and ankles, so even if it's a bit big, they can still wear it, and it lasted for two years. It was a favorite, but my child has outgrown it, so I'm selling it. I checked Amazon to see if I could buy a larger size, and it's still available for around 3900 yen. There are no noticeable stains, but since it's been worn by a child, please refrain from purchasing if you are concerned about minor details.
