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.

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.
