The CWU-7/P Liner Jacket is a quilted nylon jacket issued to U.S. Air Force mechanics and ground crews in the 1960s. Originally designed as a liner for the U.S. Air Force CWU-7/P Mechanic’s Jacket, the liner can stand on its own as an outerwear piece. Lightweight, the jacket features a zip and button enclosure providing the stability to be worn alone, yet slim enough to be layered comfortably under a jacket.
