I purchased this item here. I bought it by mistake, thinking it was down. Since I get cold easily, I haven't worn it very often, so I'm putting it up for sale. I think it will be useful in the coming season. The hem can also be opened and closed with buttons, making it easy to move around and seems convenient to use. Here's the description from the previous seller: ↓ There's no mention of the down percentage, only that the outer and inner fabrics are 100% polyester. I was told it was a down long coat by the store where I bought it. It's about 2cm thick. The store sources items from Taiwan and Korea, so please refrain from purchasing if you are concerned. When I wear it, it is very warm. The purchase price was in the tens of thousands of yen. Color: Black My impression: The length is long, which is good for keeping your legs, buttocks, and lower back warm. It feels like a thick quilted vest. Thank you. Material (Outer fabric): Polyester
