In the early 1940s, the US Navy adopted the M-421 flight jacket for summer use. This MIL-J-7758A follows on from the M-421 and was produced in the mid-1950s, taking over from the predecessor model, the AN6551. The form came from the upper body of a flight suit. The back of the jacket has action pleats that produce excellent mobility just like the Navy’s G-1 leather jacket, giving it a naval flight jacket feel. The front of the jacket, where the front zipper slider runs, represents its fine specifications such that it has a built-in cord to prevent tears from rubbing against the slider and to prevent the slider from biting into the fabric.
