Favored by bomber crews during WWll, the B-3 was brought into service around 1934. Made specifically for open cockpit and high altitude flying, the B-3 did its job admirably.  Using American Shearling, our B-3 jacket has leather welted seams, a heavy duty front zipper over a wind flap, custom authentic metal buckles and hard wear, and side entry hand warmer pockets first added by our company in 1978.  Proudly made in the U.S.A.  Available in regular and long sizes. via(Complex Magazine)
