Vintage 40s WW2 B-11 Flight Jacket Hooded Military US Army Air Forces Fur Lined. Pit to pit: 23.5. In 1943, the Army introduced the B-10, which was a revision of the A-2. The B-10 was for moderate weather so the B-11 was also released. It was a longer version meant for flights in colder weather and at greater altitudes, and it would eventually evolve into the N-3B snorkel parka.
