Sheepskin Brown Jacket in B3 Aviator Style
The B3 hasn't really changed since WWII bomber crews wore it to survive open, unheated cockpits at altitude. This version keeps that same brief: full sheepskin hide on the outside, genuine shearling left in place on the inside, built to actually hold heat rather than just reference the shape.
Because the shearling lining and the outer leather come from the same hide, the insulation isn't stitched in as an afterthought — it's part of the piece. That's what gives a proper B3 its warmth and its slouch, and why it breaks in against your body instead of sitting stiff like a synthetic-lined jacket.
B3 Jacket: Built to Last
The exterior is 1.2mm brown sheepskin leather that's designed to resist scuffing and won't crack or fade the way thinner hides do. The oversized collar turns up against wind, the zip is heavyweight YKK, and the shape is cut roomier than a standard bomber jacket, in keeping with the original flight-jacket fit — so it's worth checking our Size Guide before ordering, especially if you're between sizes.
If you want the same lineage in a different colourway, our Aviator RAF Sheepskin Men B3 Shearling Bomber Leather Jacket is cut from the same pattern.
Warm Without the Bulk
The shearling runs through the torso, arms, and collar, so heat stays in without the jacket feeling stuffy — sheepskin insulates and breathes at the same time, which is why it holds up better over a full winter than a synthetic-filled alternative.
What's included:
- Full shearling lining through the body and sleeves
- Reinforced seams at stress points for daily wear
- Hand-warmer pockets sized for gloves or small essentials
- Adjustable cuffs and hem to seal out drafts
Prefer a rougher, worn-in finish on the same silhouette? The B3 Aviator Jacket in Distressed Flight Style is the same build with a vintage treatment.
Responsibly Sourced Sheepskin
Our sheepskin is sourced from tanneries in Sialkot, Pakistan, which is what lets it hold its shape and softness season after season instead of stretching out or drying stiff. You can read more about how we select and finish our hides on our Craftsmanship page.
Wear It On or Off Duty
It works as hard in a city as it does outdoors — over denim for something rugged, or chinos if you want it to read a bit sharper. To keep it looking right: brush the shearling with a suede brush when the pile flattens, keep it away from direct heat, and have it cleaned by a leather specialist rather than a standard dry cleaner.

A few things people ask
What's the difference between sheepskin and shearling? They're the same hide — sheepskin is the whole skin, and shearling is sheepskin that's been sheared to an even, short pile and tanned with the wool left on. On this jacket, the shearling is the lining; the outer surface is the tanned leather side of that same hide.
Should I size up or down on a B3? The original was cut to layer over a flight suit, so it runs roomier than a standard jacket. Most people order their true size rather than sizing down — the Size Guide has the exact measurements.
How do I care for a shearling jacket? Keep it away from direct heat and standing water, brush the wool side when it flattens, and use a leather specialist for cleaning rather than a regular dry cleaner.
