This item can be worn as an inner down layer or as an outer jacket. It packs down compactly into its dedicated bag, making it convenient to carry. I have worn it about three times and then stored it. I have checked the item, but as it has been stored at home, there may be some minor overlooked imperfections. Please be aware of this. It's reversible, allowing you to enjoy a different look. The size is free, and I think it's equivalent to a size M to L of TAION's basic down jacket. (It feels slightly larger than M.) Size: Free - Colors: White, Camel - Materials: Down, Feather Shoulder width: 39cm Width: 48cm Sleeve length: 60cm Length: 59cm I will compress it for shipping, so please understand.
