UNIQLO Ultra Light Down Jacket, Packable, Silver, Lightweight, Size Small

This jacket is perfect for any outdoor activity that requires something lightweight and packable. It packs down into a small bag (shown in pic) making it easily fit into a backpack. It’s thin, but really warm. It looks wrinkled in the photos because it was in the bag for the last year, but the wrinkles flattened out after an hour.
