What is the B-3? In the 1930s, as aerial combat became longer-range and higher-altitude, the U.S. Army Air Corps faced an urgent need for cold-weather countermeasures. The B-3 jacket was born to protect the lives of crew members inside bomber aircraft, where temperatures could reach minus 30°C. Developed in 1934 as a flight jacket following the B-2, it was officially adopted as crew equipment. It features thick sheepskin on the exterior and shearling lining. The large collar strap and waist belt were designed for wind protection and to accommodate harness attachment. The prototype is said to be the Irvin jacket adopted by the British Royal Air Force around the same time. The U.S. military is believed to have developed a high-performance version based on its design. In the 1962 film "The War Lover," Steve McQueen, who starred in the movie, wore a B-3. The world's men were captivated not only by his scenes in the bomber but also by the effortless style and strength with which he wore it over a shirt after missions. This B-3 is a model constructed in line with vintage styles, featuring thick sheepskin on the exterior and shearling lining. It reproduces the large collar strap and waist belt, offering excellent cold protection and making it ideal for winter outerwear. The size is F, equivalent to a men's M.
