The B-15 · The Leather Version
Take the 1944 pattern.
Build it to outlast everything.
The B-15 earned its place in textile; Cockpit USA rebuilds it in oiled, deer-tanned cowhide — water-repellent, exceptionally durable, and configured to adapt. Two components remove entirely: the genuine mouton shearling collar and a zip-out poly-fill quilted vest liner, taking the jacket from deep winter to crisp fall without a second garment. Cockpit calls it the most versatile three-season jacket in their lineup. Snap-close handwarmer pockets, sleeve utility pocket, wind-flapped zipper, rib-knit trim. Made in the USA.

The oiled finish — weather protection built into the hide
The Material
Oil does
the hard work.
Deer-tanning softens the cowhide; the oiled finish seals it. The result repels water and shrugs off wear the way the textile B-15 never could.
The removables complete the system: mouton at the neck for deep cold, the quilted vest liner for the core, both gone by spring.

Versatility is
a construction choice.
Removable components double a jacket's season without diluting its identity — the B-15 silhouette stays intact whether it's configured for November or April.

What Customers Say
Questions
Before you fly.
How do the removables work?
The mouton shearling collar detaches and the poly-fill quilted vest liner zips out — each independently, so you can run any combination the weather calls for.
What does oiled, deer-tanned mean?
Deer-tanning gives the cowhide a supple hand; the oiled finish makes it water-repellent and exceptionally durable, per Cockpit.
Cowhide or nylon B-15?
The nylon is the faithful Korean War era recreation with fur collar and oxygen tabs; the cowhide is the pattern rebuilt in leather with modern removable components. History versus longevity.
How warm is it fully configured?
Collar on and liner in, it's a genuine winter leather — Cockpit rates the system their most versatile three-season jacket.
How does the sizing run?
Alpha sizes M–2XL — see the Size Guide chart for flat measurements.
Made in USA?
