Naval Aviation · The Premium G-1
Same silhouette.
Finer hand.
The G-1's shape needs no improvement — but its surface can be elevated. Deer-tanned calfskin is smoother, finer-grained, and more uniform than goatskin or lambskin at the same weight, giving this G-1 a refined appearance while keeping the structural heft of a genuine flight jacket. The quilted lining carries the pilot's escape-map applique; the mouton collar removes. The most polished jacket in the naval lineup. Made in the USA.
Deer-tanned calfskin — the finest grain in the G-1 family
The Material

Deer-tanned calfskin is smoother, finer-grained, and more uniform in texture than goatskin or lambskin at equivalent weight — refinement measured in the hand, not the label.
The structure stays: this is a flight jacket by weight and build, dressed in the family's best surface.

What Customers Say
Questions
Before you fly.
Calfskin, lambskin, or goatskin?
Goatskin is the mil-spec standard — firm, pebbled, hard-wearing. Lambskin is the softest and lightest. Calfskin sits above both: smoother and finer-grained at the same weight, with full flight-jacket structure. It's the premium pick.
What does deer-tanned mean?
A tanning method that gives the calfskin a supple, refined hand while preserving its density and durability.
Is the collar removable?
Yes — genuine mouton shearling that removes entirely, leaving a cleaner, dressier silhouette.
What's the escape map?
An embroidered and silk-screened applique in the quilted lining, honoring the survival maps naval aviators carried.
How does the sizing run?
Alpha sizes S–2XL — see the Size Guide chart for flat garment measurements.
Made in USA?
Yes — made in the USA by Cockpit USA.
