B3 Leather Bomber Jackets

The B3 leather bomber jacket was designed for one job: keeping people warm when the air turns properly cold. Today it does that job on the walk to work, the weekend away and the long winter evening outside. Every B3 jacket in this collection is cut from sheepskin with the natural wool left on the inside, so the leather takes the wind and the fleece holds your body heat. Choose from brown flying jackets, black B3 bombers, hooded and crossover-zip versions, and longer shearling coats. Each one is made to order in sizes XS to 5XL, with custom sizing when you need it, and ships free.

What Makes a B3 Leather Bomber Jacket Different

The B3 pattern dates back to the 1930s, when aircrews needed a jacket that could cope with long flights in unheated aircraft. The answer was sheepskin: one material that blocks wind on the outside and insulates on the inside. That basic idea has not changed, and it is why the B3 still works as a winter jacket nearly a century later.

You can recognise a B3 by a handful of details:

• A wide shearling collar that stands up around your neck and ears.
• Leather collar straps with metal buckles that pull the collar closed in strong wind.
• A heavy front zip, often with a storm flap or extra strap at the waist.
• A waist-length body with a roomy chest, so you can move your arms freely.
• Visible panel seams, because a single sheepskin is smaller than a full jacket, so the body is joined from several pieces.

The jackets in this collection are fashion pieces in that tradition. They carry no military insignia, badges or squadron markings, and they are not official, issued or affiliated with any air force.

Why Choose a B3 Bomber Over Other Winter Jackets

Most people shopping for a B3 are comparing it with something else. Here is how it stacks up.

Against a puffer jacket: a puffer is light and warm at first, but the fill flattens over time and the shell tears easily. A sheepskin B3 keeps its shape and warmth for many winters with basic care.

Against a wool overcoat: wool coats look sharp, but wind passes through the weave. Leather stops it. A B3 is also shorter and easier to wear with jeans and boots.

Against a regular leather jacket: an unlined or thinly lined leather jacket needs a jumper or hoodie underneath in real cold. The wool inside a B3 does that work for you.

If you want one jacket that handles serious cold, still looks good in town and lasts for years, the B3 is the practical choice. It costs more upfront than a high-street puffer, but the cost per winter usually works out lower.

B3 Styles in This Collection

Classic Brown B3 Flying Jackets

This is the version most people picture: mid or dark brown leather, cream or brown fleece, and a heavy strapped collar. Shaded and two-tone finishes give the leather depth, so it looks lived-in from the first wear. For more flight-inspired cuts, see our aviator leather pilot jackets.

Black B3 Bomber Jackets

Black leather with black or contrast fleece is a sharper, more urban take. It is easier to wear with darker clothes and works for evenings out as well as daytime.

Vintage and Distressed Finishes

Rubbed, aged and waxed finishes recreate the look of a jacket that has been worn for decades. Choose these if you prefer character over a clean, uniform surface.

Hooded B3 Jackets

A shearling-lined hood adds warmth without a hat and helps in wet, gusty weather. These suit people who spend a lot of time walking outside.

Crossover and Biker-Style Shearling Jackets

Some styles mix the B3 with a biker cut, using an asymmetric zip and a slimmer body. You keep the sheepskin warmth with a more fitted shape. These are fashion jackets, not protective riding gear.

Longer Shearling Coats

For extra coverage, the collection includes hip and thigh-length sheepskin coats with buttons or zips. They cover more of you on very cold days and pair well with smarter clothes.

Women's B3 Jackets

Women's styles are cut with a shorter body, a shaped waist and adjusted sleeves. Browse the full range in women's B3 leather jackets and women's shearling jackets.

Sheepskin, Shearling and Build Quality

The leather side. Sheepskin is supple, warm for its weight and easy to break in. Depending on the style, the outer is finished smooth, shaded, distressed or waxed. Each finish wears differently, and all of them soften with use.

The wool side. The fleece is sheared to an even length so it sits comfortably against you. Collars are usually left fuller than the body because the neck is where cold gets in first. Some styles have a removable collar; the product page will say so.

Hardware. Sheepskin is thick, so it needs strong parts. Expect heavy-duty zips, metal buckles on the collar straps and secure pocket closures.

Stitching. The panels of a B3 are joined with strong, reinforced seams, with extra attention at the shoulders, underarms and pocket corners where most strain falls.

Colours. Most styles come in brown, dark brown, tan, rust and black, with some olive and two-tone options.

Fit, Comfort and When to Wear It

Think about the days you actually need a warm jacket. A frosty morning platform waiting for a late train. A weekend in the countryside with wind coming across open fields. A trip to a cold city where you'll be walking all day and want one jacket that works from breakfast to dinner. A B3 handles all of these with a T-shirt or a light knit underneath.

How a B3 fits. The traditional cut is boxy, waist length and roomy through the chest so you can lift and reach without the jacket pulling. Because the wool takes up space inside, a B3 can feel snugger than a regular leather jacket in the same size.

Choosing your size. Measure a jacket you already own and compare it with the chart in our size guide. If you're between sizes, or plan to wear thick layers underneath, size up. If standard sizes don't suit your build, choose Custom and send your measurements.

Weight. A full sheepskin B3 is heavier than a plain leather jacket. Most people find the weight reassuring rather than tiring, and it replaces the extra layers you would otherwise carry.

Riding. These jackets are made for winter wear, not motorcycle protection. They are not CE certified and do not include armour.

How to Choose the Right B3 Jacket

• Harsh winters and lots of time outside: a classic B3 with a full strapped collar.
• City wear and commuting: a black B3 or a slimmer crossover style.
• Wet and windy weather: a hooded B3.
• Smarter outfits: a longer shearling coat or a clean black finish.
• Something lighter: a shearling-collar bomber from our men's leather bomber jackets or a classic men's leather flight jacket.
• Warmth without sleeves: a men's shearling vest.

Caring for a Sheepskin B3 Jacket

1. Never put it in a washing machine or tumble dryer.
2. Wipe light marks from the leather with a slightly damp cloth and let it air-dry.
3. If the jacket gets soaked, shake it, hang it on a wide hanger and let it dry at room temperature. Keep it away from heaters and direct sunlight.
4. Brush the wool gently every so often to keep it from matting.
5. Use a sheepskin or shearling conditioner once or twice a year to keep the leather soft.
6. Store it on a padded hanger in a breathable cotton bag, not plastic.
7. Take heavy stains to a specialist leather and suede cleaner.

Frequently Asked Questions

Are your B3 bomber jackets made from real sheepskin?

Yes. B3 jackets in this collection use genuine sheepskin with the natural wool attached. The exact material is listed on each product page.

Is a B3 jacket the same as an aviator jacket?

The B3 is one type of aviator jacket. It is the heavy sheepskin version with a strapped shearling collar. Other aviator styles can be lighter, with thinner linings or knit cuffs.

How warm is a B3 leather bomber jacket?

It is one of the warmest leather jackets you can buy, because the wool insulates and the leather blocks wind. For most winter days, a T-shirt or light jumper underneath is enough.

Should I size up in a B3 jacket?

The wool makes a B3 fit a little snugger. If you're between sizes or want to layer underneath, size up, or choose Custom and send your measurements.

Do you make B3 jackets for women?

Yes. Women's B3 and shearling jackets are cut with a shorter body and shaped waist, and you'll find them in our women's B3 and women's shearling collections.

Are the jackets made to order?

Yes. Each jacket is made after you order, which is how we offer sizes from XS to 5XL plus custom sizing.

Do you offer free shipping?

Yes, shipping is free on every order.

Can I wear a B3 jacket in the rain?

Light rain is fine. If it gets soaked, let it dry slowly at room temperature away from direct heat, then condition the leather once it is dry.
