How to Buy a B3 Bomber Jacket: Sheepskin Grade, Fit and Price

Searching for an original B3 bomber jacket usually means one thing: you want the real design, with thick sheepskin, a big shearling collar and the warmth it was built for, not a fashion jacket that only borrows the look. The B-3 was developed for American bomber crews flying at high altitude in the 1930s and 1940s, and the best modern versions still follow that pattern closely.

This guide walks you through buying one step by step: how to judge the sheepskin, how a B3 should fit, what drives the price, and the mistakes that lead to returns or regret. We also point to real B3 jackets in our store so you can compare as you read.

The Quick Answer

• Choose genuine double-face sheepskin: leather on the outside, wool on the inside, all one piece. Avoid fabric-backed "faux shearling."
• Size for a sweater underneath. A B3 is a cold-weather jacket and should not fit like a slim biker.
• Check the details that make it a B3: wide shearling collar with throat strap, waist-length body, waist belt or adjusters and heavy-duty zipper.
• B3 jackets in our collection currently start from about $200 to $330, depending on hide finish, wool depth and features such as a hood.

Step 1: Understand What Makes a B3 a B3

Plenty of jackets are called "bomber" or "aviator." A true B3 pattern has a few features that set it apart:

• Sheepskin throughout: the outer leather and inner wool are the same skin, so the whole jacket insulates.
• Large shearling collar that can be turned up and closed with straps to protect the neck and face.
• Waist-length cut so it does not bunch when you sit.
• Waist belt or side straps to stop cold air coming up from below.
• Panelled construction: sheepskin comes in smaller hides, so several panels are stitched together. Visible seams are normal and part of the look.

If a jacket has a knit collar and cuffs, it belongs to a different family. Our flight jacket guide explains how the A-2 and G-1 differ, and you can browse the wider flight jacket collection if you are still deciding on a style.

Step 2: Judge the Sheepskin

The skin is where most of the money goes and where cheap jackets cut corners. Here is what to look at:

• Genuine vs faux: real shearling has wool growing directly out of the leather. Faux versions glue or sew synthetic pile to a fabric or thin leather backing. Look at the inside of a cuff or hem: you should see wool attached to leather, not a woven base.
• Wool density: thick, even wool traps more air and keeps you warmer. Thin or patchy wool will feel cold on the back and shoulders.
• Outer finish: a waxed or distressed finish gives the classic weathered look and handles light moisture better. A smoother, sueded finish looks softer but needs more care.
• Weight: a real B3 is heavy. If a "sheepskin bomber" feels like a light jacket, it is probably not double-face sheepskin.

Step 3: Get the Fit Right

B3s fit differently from leather jackets because the wool takes up space inside. Follow these checks:

• Chest: measure your chest over the layer you will wear most, usually a sweater or flannel shirt. Then compare to the size chart for that product.
• Length: the hem should land at your waist or belt line. Longer than that and the waist strap stops doing its job.
• Sleeves: they should reach the base of your thumb with your arms relaxed, because they ride up when you reach forward or drive.
• Shoulders: expect a fuller, rounder shoulder than on a fitted jacket. That is normal for sheepskin.

If you are tall, broad or between sizes, a made-to-measure B3 removes the guesswork. We offer custom orders with a free quote, a mockup before production and one free alteration. Custom leathers include sheepskin, lambskin, goatskin, cowhide and buffalo hide. Details are on our custom leather jackets page.

Step 4: Pick the Color and Features

Brown is the traditional B3 color and looks right with denim and boots. Black is sleeker and easier to wear in the city. A hood adds wind and snow protection for very cold places. A double collar gives more shearling around the neck. Choose features for the weather you actually face, not for looks alone.

What Affects the Price of a B3 Bomber Jacket

• Type of skin: genuine double-face sheepskin costs far more than fabric-backed faux shearling.
• Wool depth and quality: denser, longer wool needs better skins.
• Finish: waxed, distressed or metallic finishes take extra work. The Metallic Gray B3 Shearling Bomber, from $329.99, is a good example.
• Features: hoods, double collars and heavy hardware add material and labor.
• Custom sizing: made-to-measure work is quoted individually.

Common Mistakes to Avoid

• Buying your T-shirt size. You will want a sweater under it, so measure over one.
• Choosing a long body. A B3 is meant to stop at the waist. Longer cuts are a different style, such as a shearling coat.
• Trusting the word "shearling" alone. Check that it is genuine sheepskin, not synthetic pile.
• Ignoring your climate. In mild areas a full B3 may be too warm for daily wear. Consider a lighter aviator leather jacket instead.
• Forgetting duties. Shipping is free worldwide by DHL, FedEx or TNT, but any import duties are paid by the customer, so factor them in.

Frequently Asked Questions

What does "original B3" actually mean?

It usually refers to the original design: a waist-length, double-face sheepskin jacket with a large shearling collar and straps. Our B3 jackets are styled on that pattern; they are newly made jackets, not military-issue surplus.

Is a B3 too warm for everyday wear?

In cold winters it is ideal. In mild climates it can be too warm for long indoor periods, so many buyers keep it for the coldest months.

Should I size up for a B3?

Not automatically. Measure your chest over a sweater and match that to the size chart. Sizing up blindly often gives sleeves that are too long.

B3 or B6: which is better?

The B3 is heavier and warmer; the B6 is lighter and less bulky. Our B3 vs B6 comparison covers the details.

Can I order a B3 made to my measurements?

Yes. Request a free quote and you will get a mockup before production, plus one free alteration.
