A bomber is a short jacket with a ribbed collar, cuff and hem, and those three ribbed points are what make the question of what to wear under a bomber jacket harder than it first looks. Anything you put underneath has to finish above the hem and lie flat at the neck. Get that right and the jacket keeps the clean, slightly boxy line it was cut for. Get it wrong and it rides up at the back, gapes at the front, or reads like outerwear borrowed from someone a size larger. Here is how to judge it, layer by layer.
What should you wear with a bomber jacket?
A fine-gauge knit is the default answer, and it is the right one most of the time. A slim crewneck sits flat across the chest, adds warmth without volume, and finishes at the hip, which means the jacket's ribbed hem still does its job of holding the shape. The Alpine Crewneck is cut light enough for this — it layers without the shoulder line thickening. The Bennett Sleeve works the same way in a long-sleeve pullover.
The practical test takes ten seconds in front of a mirror. Put both on, close the jacket fully, and cross your arms. If the front panels pull apart or the ribbed hem lifts off your hip, the layer underneath is too thick for that jacket. If you can cross your arms and the hem stays put, you have room to spare.
A collared shirt also works, with one condition: the collar has to sit outside the bomber's ribbed collar, not be swallowed by it. A soft, unstructured collar does this; a stiff, fused business collar fights it. Textured knits are worth a mention too — The Crewneck Knit carries its interest in the surface rather than in bulk, so it stays within the jacket's tolerance.
What to avoid: a hood, a chunky shawl collar, anything with a shoulder detail, and any top long enough to show below the hem. The bomber's proportion depends on the hem being the lowest point.
What to wear under a bomber jacket for women
The same rule about bulk applies, but the neckline matters more because a bomber's collar sits high and close. A mock neck or a half-zip reads deliberate under it — The Willow Zip Knit gives you a neckline you can adjust, which is useful when the jacket collar is fixed. Zip it up and you get a clean column; drop it and the knit reads softer against the rib.
A fine sweater in a warm mid-tone, such as The Vesper Sweater, does the other useful thing: it breaks up a dark jacket over dark denim so the outfit is not one unbroken block. If you want the jacket to be the quiet part, keep the layer beneath it lighter than the shell.
Length is the usual failure point. A bomber ends at or just below the hip, so a longer top underneath will show and flatten the silhouette. If the top is longer, either tuck it or choose a different jacket — a straighter cut from the women's jackets range handles length better than a bomber does.
Can a 50-year-old man wear a bomber jacket?
Yes, and the variables that decide it have nothing to do with age. Three things make a bomber read young: a glossy shell, visible branding, and a cropped, tight fit. Remove those and you have a short jacket with a clean line, which is simply a jacket.
A matte shell is the single biggest lever. The Bomber Jacket uses a matte nylon that absorbs light rather than catching it, which is what keeps it out of sportswear territory. Pair it with a knit rather than a hoodie, trousers rather than joggers, and a leather-look boot or a clean loafer, and the question answers itself.
The fit rule: the hem should sit at your hip bone, not above it, and the shoulder seam should land where your shoulder ends. A bomber that finishes at the waistband looks borrowed; one that finishes at the hip looks intentional.
Are bomber jackets still in style in 2026?
The bomber has been in continuous production since the 1950s and has never fully left, which is a useful signal in itself: garments that survive that long tend to do so because the shape solves a problem rather than because it is fashionable. A short jacket with a closed hem keeps warmth in without adding length, which is precisely what a mild autumn asks for.
What does change is the detailing. The current preference across European menswear is for matte finishes, muted colours and no visible branding, which is where a plain black or navy shell sits comfortably. Loud patches, satin finishes and heavy embroidery date faster because they belong to a specific moment rather than to the shape.
If you are deciding how many pieces of outerwear are worth owning at all, that question is worth its own answer — see how many jackets you really need. And if you want to compare a bomber against the rest of the range before committing, the full men's jackets collection is the place to start.
