Product History

The U.S. Navy started making the G-1 leather jacket (originally known as the M-445 flight jacket) during the Second World War. The jacket was form-fitted with a longer waist webbing at the bottom, a bi-swing back for easier arm movement and a Mouton collar. The G-1 used button closures on the front pockets. It was made until 1978 when Congress cancelled it due to its popularity and lack of supply. It was produced again during Desert Storm and is still issued today. Alpha is proud to make this iconic leather bomber.

How to Measure:

Men's Measurement Guide

Measure around base of neckline, keeping one finger between your neck and the measuring tape.


Measure around body with tape leveled on the fullest part of your chest.


Measure around your waist with the tape leveled at the narrowest point of your torso.


With arm relaxed at your side, measure from center back neck, to point of shoulder, and along the arm to the wrist (just below round bone).


Stand with heels 2—3” apart. Keep the tape leveled and measure around the fullest part of your hips.


Measure pants that fit you well, and feel comfortable. Lay pants flat on table, and smooth the front and back crease. Measure along the inseam from crotch to bottom of edge of hem.
