This is an adidas hoodie. It's practically new. I bought it because I was drawn to the slightly muted, beautiful light blue color, but I've kept it stored away. I've only worn it once for a short time. I'm also including sweatpants that I bought to match the color. These are a no-brand item, but they are made of a fabric that feels comfortable. There is no Japanese size listed, so I'm estimating it to be roughly equivalent to a size M, and will list it as such.
