Who is not aware of the Vietnam war, that is one of the coldest and intense wars of the world. It was basically between the United States and the Soviet Union which certainly pitted the government of South Vietnam against North Vietnam. Before this war, pilot jackets were famous among war pilots, made of top-grain leather and lined with full fur shearling in order to protect them from cold and harsh climatic changes. Afterward, these jackets were taken to a new origin and named the Vietnam Pilot Jacket. With the slight change in their tailoring, they were categorized in entirely different ways from the previous pilot bombers. They are not tailored with the shearling inner but their top-grained leather surface makes them durable and warm enough for the pilots to endure the cold snowy winds.
