This collection is for shoppers who want the B3 specifically, not just any warm leather jacket. The listed products are mainly men’s styles, built around the B3’s key features: a cropped waist-length body, a deep shearling collar, a zip front and a wool-lined interior.
Product materials vary, and it’s worth checking. The Brown B3 Bomber, for example, lists a sheepskin leather outer with a wool lining. The Black Leather B3 Bomber Jacket uses lambskin with a faux shearling lining. Each product page shows the outer and lining materials.
For the wider range of wool-lined outerwear, browse sheepskin jackets and shearling jackets. Women shopping for a similar look can explore women’s aviator jackets.
In the 1930s, bomber aircraft flew higher than ever, but their cabins were still unheated and often open to the wind. The US Army Air Corps needed a jacket that could keep crews functional at freezing altitudes, so it adopted the B-3 in the mid-1930s. Made from heavy sheepskin with the wool worn inside, it had a large collar that could be strapped closed over the neck and lower face.
The B-3 was worn by American bomber crews into the Second World War. Later, lighter flight jackets, such as the B-6, also came into service. After the war, surplus jackets and civilian versions brought the B3 to everyday wardrobes, where it has stayed ever since. Read more in the history and allure of the B3 aviator shearling jacket.
Knowing the key features makes it easier to compare jackets and spot a true B3 cut.
These are the core B3s: cropped, wool-lined and built around a wide shearling collar. Choose from the Men’s Brown B3 Bomber Shearling Sheepskin Jacket, the Men’s Black B3 Bomber Shearling Sheepskin Jacket and the Men’s Classic B3 Air Force Sheepskin Shearling Jacket.
Some B3s borrow details from British flying jackets, such as different paneling or collar shapes. The Men’s Dark Brown B3 RAF Aviator Sheepskin Shearling Jacket and the Men’s Black B3 Shearling Flight Aviator Jacket blend both traditions. For more aviator cuts, browse aviator jackets.
A hood adds an extra layer of protection on windy or snowy days. Options include the B-3 Hooded Sheepskin Leather Bomber Jacket and the Men’s B3 Sheepskin Jacket with Detachable Hood, which is listed with real sheep fur lining through the sleeves.
If you love the B3 collar but want more coverage, the Men’s B3 Double Collar Shearling Aviator Long Coat extends the flight-jacket design below the hip. For more long styles, see men’s sheepskin coats.
The B-6 is a lighter flight jacket that followed the B-3. The Men’s B-6 Shearling Bomber Jacket suits shoppers who want the flight-jacket look in a less bulky style.
This brown B3 is a classic place to start. It’s listed with a sheepskin leather outer, a wool lining, a turn-down collar, a zip closure and a slim cut. Sizes run from S to 4XL, with a Custom option if you want it made to your measurements. Brown is the traditional B3 color and shows the contrast between leather and wool collar well.
These names often appear together but describe different jackets. A B3 is a heavy, cropped sheepskin flight jacket with a large strapped collar. A B-6 is a lighter sheepskin flight jacket. An A-2 is an unlined or lightly lined leather flight jacket with a shirt-style collar and no shearling, so it’s a different jacket entirely. Aviator jacket is a broader term for flight-inspired jackets, including B3s and RAF-style designs. Bomber jacket is the widest term and includes many styles, both with and without shearling.
Brown is the most traditional B3 color. The leather and pale wool collar together create the vintage flight-jacket look that most people associate with the B3. See more in men’s brown leather jackets.
Dark brown feels deeper and slightly more refined than classic brown. It works well with dark denim, charcoal trousers and heavier knitwear.
A black B3 looks more contemporary and urban, especially with a darker collar. It suits all-black outfits and city winters. Browse more in men’s black leather jackets.
A B3 is designed to be cropped, so don’t expect it to cover your hips. The hem should sit at or just above your waist. Measure your chest, shoulders and sleeve length and compare them with the 3amoto size guide.
Because the wool lining adds thickness, think about what you’ll wear underneath. If you plan to wear a heavy sweater, you need more room through the chest and arms than you would over a T-shirt. Make sure the collar can close comfortably with the straps fastened, and check that the sleeves still reach your wrists when you reach forward. If you’re between sizes, choose the Custom option or made-to-measure ordering.

A genuine sheepskin B3 has the wool attached to the hide, so the lining is natural wool. Wool is known for trapping warm air and handling moisture well, which is why sheepskin was originally chosen for flight jackets. It’s usually heavier, more expensive and requires specialist cleaning.
A leather B3 with a faux shearling lining, such as the Black Leather B3 Bomber Jacket with a lambskin outer, gives you the B3 look at a lower price. These jackets are often lighter and easier to care for, but the lining doesn’t perform like natural wool.
Both options have a place. Check the product specifications so you know which one you’re buying.
