G-1 Jacket – USN

The Navy’s first carrier landing was made on October 26, 1922, when Lieutenant Commander Godfrey Chevalier brought an Aeromarine biplane aboard USS Langley. Today, the Navy’s aircraft carriers are more than three football fields long and their jets are heavy, fast, and devastatingly effective.

Naval Aviators haven’t changed, though. They demonstrate the same quiet, steady courage and competence as they catapult off the bow and return to trap the 3-wire on a rolling, pitching deck.

Naval Aviators’ love of their leather flight jackets hasn’t changed either. The G-1 jacket is one of the most coveted possessions of Naval Aviators.  Most G-ls are covered with squadron, carrier, and aircraft patches from the aviator’s duty assignments.

First issued in 1938 as the M422 and renamed the AN-J-3a in 1943, the Navy’s famous flight jacket became the G-1 in 1951.

Gibson & Barnes follows the original Navy specifications and patterns for the G-1.  We make it from large drum-dyed, semi-aniline goatskins and use genuine mouton (lamb’s wool) for the collar, rib knit for the cuffs and waistband, and a heavy solid brass zipper.

Quick inspection of your jacket shows the utmost attention to detail and quality.  Roll the collar up on your G-1 and you’ll notice the gracefully curved throat latch. There is a carefully sewn pencil pocket under the left pocket flap, “USN” cleanly punched into the storm flap, and a snap-shut interior pocket for your charts and gear. The recoiling swing back in the leather and lining gives you complete lateral movement and double gussets under each arm allow greater vertical reach.

Leather Color

Gibson & Barnes uses grade A and B leather even though it can cost twice as much as lower grades.  Your jacket will be more beautiful and will last longer because high quality hides need only a light coat of pigment.

We also use large hides so we can make your jacket with fewer pieces.  Many of our jackets have one-piece backs, and our sleeves are cut from only two pieces of leather.  We also throw away our scrap leather and don’t try to hide it under the collar or under a pocket flap.  Your jacket will look better, feel better, and last longer.

Goatskin is perfect jacket leather because it is durable as well as supple, soft to the touch, and very comfortable to wear.  Goatskin jackets last so long they are passed down from generation to generation.  We’ve seen goatskin jackets at look even better after 50 years of wear man they did when new.  Both the Navy and Air Force use goatskin for their G-1 and A-2 flight jackets.

Leather Terminology

Chrome Tanned – Leather preserved with chromium compounds and other mineral agents to produce supple leather for garments, shoes, and gloves.

Vegetable Tanned – Leather preserved with tannins from ‘bark, seeds, and wood to produce strong and slightly stiff leather for luggage and belting.

Drum Dyed – Leather dyed in a rotating drum so that the dye completely penetrates the leather.

Aniline Dyed – Leather dyed with transparent aniline dyes to produce a beautiful transparent finish and suppleness.  No pigment is used, but a light finish may be applied to color or protect the leather.

Semi-Aniline – Aniline dyed leather topped with a very light coat of pigment and finish to even out the color and increase durability.

Pigmented – Leather coated with resin containing pigment.  Pigment gives leather a uniform color and shade.  Low-grade leather needs thick coats of pigment to cover up cuts and scars.

Thickness – Leather thickness is measured in millimeters or ounces per square foot.  One-ounce equals about 1/54 inch or 0.40 millimeters thickness.  Jacket leather is usually between two and four ounces.

Top Grain – Leather from which only the hair and under flesh have been removed.  It is a higher quality leather.

Split Grain – The lower-quality bottom layer of a skin that has been split into a top and bottom layer.   The bottom layer can be made into suede or highly pigmented to give it the appearance of top grain.

Grade – Leather grades range from A to D depending on the type and number of flaws.  Grade A hides are clean with no flaws.  Grade B has a few slight imperfections.  Grade C has healed cuts.  Grade D has unhealed cuts.  The higher the grade, the less pigment needed to finish the leather and the

more beautiful the finished jacket.

Shearling – Sheepskin with the wool attached.  The wool can be straightened or left naturally curly.

Mouton – Sheepskin with the wool attached that has been sheared and dyed to resemble beaver or seal.
