This is a Patagonia outerwear item purchased from an authorized retailer. It's a Boy's L size, but it probably fits like a Women's S to M size. For me, who usually wears a Women's M, the outer layer has a little room, and the inner layer fits perfectly. (Reference: Height 160cm, average build) The inner layer has been used a few times around the neighborhood. It's very warm! It's a design that can be used as a quilted jacket even for everyday wear. There are some minor stains on the inside of the collar and cuffs, so please be aware of this. Overall, I personally think it's in very good condition, but there are a few black stains. Please understand this. The following is a quote from the website: A waterproof/breathable jacket that can be worn across seasons.
