The U.S. Air Force flight jacket has had numerous variations in the past. Among these flight jackets, the most famous model is the MA-1. The MA-1 is a nylon flight jacket developed for pilots by the U.S. Air Force, which was established after World War II, independent of the Army Air Forces. Even within flight jackets, the jackets worn differ depending on the altitude. Therefore, there are various jackets based on temperature zones, known as "zone types." The main zone types are "Light Zone (10°C to 30°C)", "Intermediate Zone (-10°C to 10°C)", and "Heavy Zone (-10°C to -30°C)". The MA-1, worn for the Intermediate Zone, which is the most frequently active zone, was so well-made that it later spread to ground crew members as well as pilots. The cockpits of fighter jets are narrow, surrounded by various equipment, and have many protrusions such as levers and switches. Therefore, the MA-1 was created as a jacket that would not burden the pilot's body, was comfortable to wear, easy to move in, and had excellent functionality such as storage, durability, insulation, and water resistance. It is said to be a masterpiece of flight suits. When you think of the MA-1, many people associate it with the orange lining, but the fact that there are many variations depending on the era is also a characteristic of the MA-1. Among them, WAIPER has recreated the most initial details of the MA-1, focusing on the same-colored lining, a chest box tab, and ICS cord loops on both sides.
