Seal-brown military-spec goatskin with a genuine WWII-pattern mouton collar — the Navy's materials since 1940.
The Navy's jacket.
"USN" wind flap, bi-swing back, no side-entry pockets — the regulation configuration, not a fashion cut.

You’re looking at it
I've had a number of military style (G-1 and A-2) jackets. But this is the first Cockpit USA jacket I've ever owned and it is the best of the lot.
The leather quality is top notch, the natural fur collar is a plus, no sissy hand pockets, heavy duty zipper, quality construction, wind flap works. I served on a carrier and always had flight jacket envy.
If you see how these are worn by aviators on active duty it actually fits as intended. Just enjoy an amazing, American made product.
Very nice leather and the quality of the craftsmanship seems impeccable. Very true to the original design.

Before you fly.
Is this historically accurate?
Yes — seal-brown goatskin, genuine WWII-pattern mouton collar, bi-swing back, USN wind flap, and no side-entry pockets, per the Navy specification.
Why no handwarmer pockets?
The USN specification never included side-entry pockets, so the mil-spec jacket doesn't either.
How does the sizing run?
Regular fit on the military pattern, with the shorter aviator length. Between sizes or broad-shouldered? Verified buyers consistently recommend sizing up.
Is the collar real fur?
Genuine mouton (sheep) fur with button closure, per the original spec. The collar is fixed on this model.
Is this the Top Gun jacket?
The G-1 is the jacket type Tom Cruise wore in Top Gun (1986). This is the clean regulation version — the patched movie configuration is the Reproduction Top Gun G-1.

Naval Aviation · Issued Since 1940
Eighty-six years on flight status.
Still built to the specification.
In March 1940 the U.S. Navy issued specification M-422: a goatskin intermediate flight jacket with a mouton collar and a bi-swing back. It flew through WWII — and as the G-1, it has remained standard issue gear of the U.S. Navy ever since. Cockpit USA builds this jacket to the military-spec pattern in the USA, working from original military designs as it has since 1975.
Seal-brown military-spec goatskin · genuine mouton collar
The Material
Military-spec goatskin.
The Navy's hide since 1940.
Every specification of this jacket — from M-422 in 1940 to today's MIL-DTL-7823F — has called for the same thing: uniform seal-brown goatskin. Cockpit USA cuts this G-1 from 100% military-spec goatskin.
The collar is genuine mouton fur on the original WWII-era pattern, closed with buttons — not a synthetic substitute. Inside: nylon lining with an interior snap pocket.
Construction
Regulation, not interpretation.
"USN" wind flap
The front zipper closes over a wind flap perforated "USN" — the Navy's mark, cut into the jacket itself.
Bi-swing action back
The pleated back the spec has required since 1940: full reach in a cockpit, no ride-up.
Vented underarm gussets
Underarm gussets with ventilation holes move air and free the shoulders.
Button-down flap pockets
Two front flap pockets with button closure, plus a hidden pencil pocket.
No side-entry pockets
The USN specification never had handwarmer pockets. Neither does this jacket.
Knit waist and cuffs
Elastic knit waistband and cuffs seal the intermediate zone the jacket was built for.

The best of the lot
I've had a number of military style (G-1 and A-2) jackets. But this is the first Cockpit USA jacket I've ever owned and it is the best of the lot. The quality of the leather is exceptional.
After 4 years plus
The leather quality is top notch, the natural fur collar is a plus, no sissy hand pockets, heavy duty zipper, quality construction, wind flap works. I served on a carrier and always had flight jacket envy. If you are looking for a quality civilian replica of a G-1, this is an excellent choice.
An amazing, American made product
If you see how these are worn by aviators on active duty it actually fits as intended. You will get the Top Gun jokes once in a while, but they're really just jealous.

Why are there no handwarmer pockets?
