The hood does not detach. There are two pockets on the inside. It's a thin down jacket. The color is navy, like a darker version of the first photo. It might be close to a dark blue-purple. The sheen is similar to that in the 6th and 7th photos. Outer fabric: 100% polyester Filling: 62% down, 30% polyester, 8% feather Lining: 100% polyester Thank you for viewing. Shipping will be via Nekopos or Yu-packet Post, packed flat in a stock bag. Please examine the photos carefully before purchasing, as this is a used item.
