The M-422 and M-422A Pilot Jackets (1941): the ancestors of the G1 jacket
Before the appearance of the mythical G1 jacket , worn by Navy pilots and immortalized by Hollywood, there were two foundational models: the M-422 jacket and its improved version, the M-422A .
These flight jackets, introduced at the beginning of the Second World War, are the true precursors of the G1 and occupy an essential place in the history of military aviator jackets .

The origin of the M-422 jacket
In 1940 , the US Navy officially introduced the M-422 as the standard issue jacket for its pilots and crews.
At a time when the US Army Air Corps was adopting the A2 jacket, the Navy needed a model better suited to the particular conditions of naval air missions: cool temperatures at altitude, humidity at sea and the need for comfort in cramped cockpits.
The M-422 was characterized by:
-
A collar made of real fur (often sheep or goat), wide and protective.
-
Goatskin leather , supple but very resistant.
-
An inner wool lining for added warmth.
-
A waist and cuffs made of elastic knit to block the wind.
-
Two patch pockets with flaps and snap buttons.
This design laid the foundation for the entire line of US Navy pilot jackets .

The evolution towards the M-422A jacket (1941)
Very quickly, the Navy improved the initial model and in 1941 adopted the M-422A jacket , which corrected some details of the first model.
Notable differences include:
-
A slightly resized collar , sometimes with an additional retaining button.
-
An extended collar tab , for even better protection against the wind.
-
Reinforced pockets , stronger and more practical.
-
An even more robust leather , guaranteeing better durability in extreme conditions.
The M-422A was produced and worn throughout World War II by pilots and crews of the US Navy and Marines. It is now considered the "mother" of the G1 , since the latter adopted virtually the same design after 1947.

The M-422 and M-422A in the history of aviator jackets
These two models are essential because they mark the Navy's transition to a distinct dress identity , different from the US Army Air Corps.
Where the A2 represented the air force pilots, the M-422 and M-422A embodied the spirit of the aviators embarked on aircraft carriers, facing long and perilous missions.
Their design, a blend of military robustness and timeless elegance , explains why they are still sought-after pieces for collectors and history enthusiasts today.
The M-422 and M-422A jackets today
The originals from 1941 are extremely rare and command high prices on the collectors' market.
However, several brands specializing in vintage pilot jackets offer faithful reissues , respecting the materials and cuts of the period.
Wearing an M-422 or an M-422A is wearing a piece of history: that of the first US Navy pilots in the midst of World War II, at the dawn of a legend that would continue with the G1 jacket .
Conclusion: a direct legacy of G1
The M-422 and M-422A jackets are the true ancestors of the G1 pilot's jacket. Introduced as early as 1940-41, they combine functionality, protection and elegance , and embody the spirit of Navy aviators during World War II.
Even today, they remain iconic aviator jackets , coveted by collectors and admired by military fashion enthusiasts.
