Cockpit USA B-3 vs A-2: Which Is Right for You?

When people discover Cockpit USA, the first question is almost always the same: should I get the B-3 or the A-2? Both are legendary pieces of American aviation history. Both are made to military specification. But they are built for completely different conditions, and the right choice depends on where you live, how you'll wear it, and what you're looking for.

What Is the B-3?

The B-3 bomber jacket was developed for World War II bomber crews who flew in unpressurized, unheated aircraft at altitudes where temperatures dropped to -40°F or colder. The solution was shearling — real sheepskin with the wool left intact on the inside. The B-3 is essentially a wearable sleeping bag. It is massively warm, deeply insulating, and built for extreme cold-weather performance.

Cockpit USA's B-3 models include the Pearl Harbor reproduction — a period-correct WWII replica — and the 100 Mission, which adds unique commemorative details. Both use genuine sheepskin shearling. The outer shell is leather. The collar is oversized and can be fastened up around the face. This is the warmest jacket Cockpit USA makes.

What Is the A-2?

The A-2 flight jacket was the standard-issue jacket for Army Air Forces pilots in World War II. It's a leather bomber jacket — sleek, fitted, with a zippered front, knit cuffs and waistband, and a snap collar. It's the jacket you've seen on everyone from General Jimmy Doolittle to Harrison Ford as Indiana Jones. The A-2 is versatile, can be worn three seasons, and has a much slimmer profile than the B-3.

Cockpit USA is the official USAF supplier of the A-2 jacket. Their USAF A-2 uses genuine goatskin. They also offer the Flying Tigers A-2 in horsehide — one of the most visually striking versions available anywhere. The A-2 is lined but not insulated with shearling, making it suitable for cool-to-cold weather rather than extreme cold.

Key Differences at a Glance

Warmth: B-3 wins by a wide margin. The shearling lining provides genuine extreme-cold insulation. The A-2 is warm but suited for fall and mild winter use, not sub-zero conditions.

Versatility: A-2 wins. The slim profile, sleek styling, and lighter weight make the A-2 wearable in more contexts — casual, semi-formal, riding, travel. The B-3 is a statement piece best suited to cold weather.

Historical Significance: Both are equally significant. The B-3 saved lives at altitude. The A-2 became the defining image of WWII aviation. Neither loses on this measure.

Price: B-3 models cost more due to the shearling material and bulk. The A-2 is more accessible at the lower end of Cockpit USA's range.

Which Should You Buy?

If you live somewhere with genuinely cold winters and want the most impressive, warm, and historically evocative piece in Cockpit USA's lineup, get the B-3. The Pearl Harbor and 100 Mission models available at Legendary USA are both excellent choices. If you want a jacket you can wear year-round in most climates, that pairs with jeans, motorcycles, and civilian life equally well, get the A-2. The USAF A-2 in goatskin or the Flying Tigers in horsehide — both available at Legendary USA — are among the best flight jackets made in America today.
