B3 Bomber Shearling Jacket
Men's B3 Bomber Jackets
The B3 Bomber Jacket is a historic article that has been with us since World War II — originally designed for US Army Air Corps and Royal Air Force pilots flying at altitudes where temperatures dropped to -40°F in unpressurised cockpits. It is specifically designed to keep you genuinely warm rather than fashion-warm — the difference being a jacket that performs in real sub-zero conditions rather than simply looking like it would.
The secret is in the construction. Every genuine B3 Bomber Jacket is built from double-face sheepskin — where the leather exterior and the natural wool interior are one single integrated hide rather than two separate materials bonded together. The leather acts as a windproof primary barrier. The wool thermoregulates — warming when cold, venting excess heat during active movement — in a way that no synthetic fill or bonded lining can replicate. This is why genuine B3 jackets are rated to -20°C in our core range and -25°C in the B3 Long Coat — not because of clever marketing but because genuine double-face sheepskin is the most thermally efficient natural insulation ever used in outerwear.
Usually B3 Bomber Jackets are made of genuine leather which makes them exceptionally durable. They feature the signature dual-strap storm collar that can be buckled high to shield the neck and lower face against freezing wind — the detail that separates a true B3 from a fashion interpretation. Most feature a heavy-duty front zipper, two exterior cargo-style pockets, and one or two internal security pockets. The waist adjustment buckles allow you to cinch the fit and prevent cold air from entering through the hem — every construction detail exists for a functional reason rooted in the original military specification.
How to Choose the Right B3 for Your Climate
Not every B3 in this collection is built for the same temperature. Here is how to navigate the range.
For -5°C to 8°C — our classic B3 aviator styles with standard shearling lining are the correct choice. Warm enough for a genuine winter commute without being restrictive in slightly milder conditions.
For -10°C to -5°C — our B3 RAF Flying Fur Collar Jacket with the oversized fur collar adds the critical neck and lower face protection needed when temperatures drop into genuine sub-zero territory.
For -20°C and below — the B3 Long Coat extends the sheepskin construction from shoulder to mid-thigh providing full core and lower-body protection in the most extreme winter conditions.
Colours and Styles
There are different colours available across the range but black and brown bomber jacket styles remain our top sellers — brown being the historically accurate colourway of the original WWII B3 and black being the contemporary urban interpretation that carries the same construction in a more versatile modern aesthetic. Both are available in genuine double-face sheepskin. Both perform identically. The choice is purely aesthetic.
This versatile piece of clothing works across more occasions than most buyers expect — worn open over a turtleneck for a smart-casual urban look, worn fully buckled for extreme cold weather commuting, or layered over a motorcycle jacket as a thermal core piece. The B3 does not restrict itself to a single context because it was never designed for one.
Why Direct from Shearling Leather
Every B3 jacket in this collection is manufactured directly — no wholesale margin, no retail markup between the tannery and your wardrobe. The genuine double-face sheepskin you receive is the same material grade used in premium outerwear brands at three times the price. The difference is the brand tax — which you do not pay here.
In conclusion a B3 Leather Bomber Jacket is a must-have piece of leather wear in every serious wardrobe — not because it is fashionable but because it is genuinely the warmest and most durable natural-material jacket ever designed. A jacket this well-engineered does not go out of style because it was never in style — it was always simply correct.
