Still by Hand - Loop Button Vest - Ink BlackStill by Hand produce some beautiful clothing that looks simple at first but is anything but. Clean, sure but packed with features and high quality finishes that raise this stuff to classic status. The loop button vest is made from a cotton nylon blend fabric that feels like a high density cotton twill with a washed finish. The loop button closure is ironically actually designed to look better open as you can see the full detail of the loop features.
