Originally designed to keep WWII flight crews warm and safe during long-haul, high-altitude bombing runs, the B6 offers a tweaked and streamlined update on the iconic B3.


The B6 was introduced in the early ‘40s as an update to the bulkier B3 and incorporates several improvements in pattern and manoeuvrability. Namely, the B6 features a bi-swing “action” back for a fuller, uninhibited range of motion. The jacket also scales down the fur collar, and reduces the number of leather panels used. The drop pockets are replaced with handwarmer slash pockets.

As we’re no longer wearing these jackets to stick it to The Axis, the differences between The Real McCoy’s B3 and B6 iterations are largely aesthetic—both offer peerless protection against the winter cold.

For their reproduction B6, The Real McCoy’s have referenced their extensive archive of leather bombers—paying particular attention to how these historic jackets have withstood the rigours of warfare and time. They’ve upgraded things along the way too, replacing the original ¼” hide with a superior ½” combination-tanned sheepskin. This lustrous leather has been custom-lacquered to emulate the look and feel of a vintage B6 whilst retaining exceptional strength, insulation, and durability.

Each jacket is made—start to finish—by a single pair of hands at The Real McCoy’s Kobe atelier. All hardware is custom-made to emulate the look, feel, and charm of the ‘40s original. Not to overstate things, but this is a jacket that’s likely to outlive you. It's a true heirloom piece.

Important: The best way to determine the size you need is to measure a similar item you already own and compare with the actual sizing as per the table below. Do not go by tagsize alone.

Please note: Exterior measurements such as the shoulder and chest will appear larger than tag sizes suggest on account of the jacket's thickness and lining.
