Naval Aviation · The Winter G-1
Built for the season
other jackets sit out.
Most G-1s are three-season jackets. This one isn't. Under its all-black goatskin shell runs a melton wool body lining — the dense, tightly-milled cloth that makes this the warmest G-1 in the lineup. The naval bones are all present: mouton button collar, bi-swing back with gussets, USN-style wind flap, button-flap pockets with hidden side-entry handwarmers. Cut to a true trim military fit in numeric sizes 36–52. Made in the USA.
Pebbled goatskin in all black — collar, zip, and flap pocket
The Material
Goatskin outside.
Wool inside.
The shell is the G-1's proven hide — pebble-grained goatskin — finished in black. Inside, a melton wool body lining replaces the usual lightweight cloth.
That wool is the point: dense, warm, and quiet, it turns the naval silhouette into a genuine winter jacket — the warmest G-1 in the lineup.
Construction
The G-1, winterized.
Mouton button collar
Genuine shearling, buttoned down against the wind.
USN wind flap
Front zip under the Navy's perforated wind flap.
Bi-swing back + gussets
The action back, with underarm gussets for reach.
Hidden handwarmers
Button-flap pockets, concealed side-entry handwarmers, and a pencil pocket.
Melton wool body lining
The winter upgrade — dense milled wool through the body.
Elastic knits · tapered sleeves
Knit cuffs and waistband; sleeves tapered to the trim cut.

The Submariner isn't a lined G-1 — it's a G-1 rebuilt around its lining. Melton wool through the body, mouton at the neck, goatskin outside: three materials, one winter jacket.

What Customers Say
Questions
Before you fly.
How warm is it, really?
The melton wool body lining — dense, tightly-milled wool cloth — makes this the warmest G-1 in the lineup. If you want the naval silhouette for genuine winter, this is the one.
How does the trim fit run?
True trim military fit with tapered sleeves, numeric sizes 36–52. If you're between sizes or plan to layer underneath, size up.
Submariner or Mil-Spec G-1?
The Mil-Spec is the regulation three-season jacket in brown goatskin. The Submariner trades the light lining for melton wool and goes all black — same family, winter division.
Where are the handwarmer pockets?
Hidden side-entry handwarmers sit behind the button-flap front pockets, with a pencil pocket besides.
Is the collar removable?
No — the mouton collar buttons down and stays. It's part of the winter build.
Made in USA?
Yes — made in the USA by Cockpit USA.
