The Type B-10 jacket, recreated by Buzz Rickson's, is a faithful reproduction based on the iconic vintage design used by the U.S. Army Air Forces during WWII. Initially adopted in 1943, the B-10 jacket was developed as a fabric alternative to leather flight jackets to counter a leather shortage. It features water-resistant cotton twill fabric with an alpaca and wool pile lining for warmth, ideal for temperatures ranging from +10°C to -10°C. This special edition includes hand-painted insignia representing the 380th Bombardment Squadron on the back and a leather patch with the 529th Bombardment Squadron insignia on the front. Classic WWII-inspired fit, crafted for durability and a comfortable range of movement.
