Classic Men's B-3 Sheepskin Shearling Leather Bomber Jacket
Classic Men's B-3 Sheepskin Shearling Leather Bomber Jacket
At 25,000 feet over Europe, the bomber crews of the Second World War faced a cold most people will never experience — temperatures far below freezing, in unpressurised, unheated aircraft, for hours at a time. The jacket that kept them alive up there was the B-3. Thick sheepskin on the outside, dense natural shearling on the inside. No electronics, no synthetic insulation — just the warmest natural material the era could offer, cut into a jacket built for survival.
Eighty years later, the B-3 hasn't changed much — because it never needed to. This is that jacket, faithful to the original: a heavyweight brown sheepskin shell with a rich, lived-in finish, lined fully in genuine cream shearling that runs from the collar down through the body, out to the cuffs, and along the hem.
The warmth is the whole story. Natural shearling traps body heat the way few materials can, and on the B-3 it's not a trim detail — it's everywhere. The wool collar pops up to seal around your neck, secured by a throat-latch strap straight from the military pattern. The cuffs and hem are wrapped in the same thick wool, closing off every gap where cold tries to get in. Two adjustable side-buckle tabs at the waist let you cinch the jacket close to lock the heat in. This is genuine cold-weather outerwear — the jacket you reach for when winter stops being a style consideration and starts being a real one.
What's remarkable is how the B-3 carries all that function without looking purely utilitarian. The cracked, vintage-finished sheepskin shell has the kind of character that synthetic puffers will never have. It looks rugged and substantial, with the unmistakable presence of a heritage piece. Worn open over a dark tee and chinos, as the photos show, it reads as confident, lived-in, and timeless — a jacket with a story, not just a spec sheet.
Some jackets are designed for mild weather and styled to look warm. The B-3 is the opposite. It is genuinely, seriously warm — and it happens to look like a legend while doing it.

Frequently Asked Questions
What is a B-3 jacket? The B-3 is a heavyweight sheepskin shearling flight jacket originally issued to US bomber crews in the Second World War. It was designed for extreme cold at high altitude, and is recognised by its thick shearling collar, cuffs, and lining, and its substantial, structured cut.
Is the shearling real? Yes — this jacket features genuine sheepskin and natural shearling. The wool you see at the collar, cuffs, and hem is the same shearling that lines the entire interior of the jacket.
How warm is this jacket? Very. The B-3 is one of the warmest jacket styles ever made. The full natural shearling lining traps body heat extremely effectively, and the shearling collar, cuffs, and hem seal out cold air. It is built for genuinely cold winter conditions — not mild-weather layering.
What temperatures is it suitable for? The B-3 is a true cold-weather jacket, well suited to deep winter and freezing conditions. In milder weather it will likely feel too warm — this is heavy-duty outerwear, not a three-season piece.
Does it fit true to size? The B-3 has a heavy, structured cut and the thick shearling lining takes up interior room. It's designed to be worn over lighter layers like a tee or thin knit rather than bulky sweaters. If you're between sizes, check the size chart on this page carefully before ordering.
How do I care for sheepskin and shearling? Brush the shearling gently with a suede or wool brush to keep it lofted. Spot-clean the sheepskin shell with a damp cloth and use a sheepskin-specific protector. Never machine wash, never soak, and never use direct heat to dry. For deep cleaning, use a specialist experienced with sheepskin.
Is it heavy? Yes — genuine sheepskin and full shearling make the B-3 a substantial, heavy jacket. That weight is part of what it is: real materials, real warmth, real presence. It is not a lightweight jacket and isn't meant to be.
Can I wear it in the rain? Sheepskin handles light exposure, especially with a protector applied, but it should not be worn in heavy rain. If it gets wet, let it air dry naturally away from heat, then brush the shearling back up once dry.
Will the cracked finish on the leather get worse? No — the cracked, vintage look is an intentional finish, part of the B-3's heritage character. It won't deteriorate with normal wear; it simply gives the jacket its authentic, lived-in appearance from day one.
