A gilet is a sleeveless outer layer designed to add warmth around the body without restricting the arms. It sits between knitwear and a jacket, making it useful for transitional weather and layered winter outfits. In the UK you will also hear it called a body warmer, which is the same thing.
Gilet meaning and how to say it
“Gilet” is a French word that British English has borrowed for a sleeveless jacket. It is usually pronounced “zhee-lay” or “jee-lay”, with a silent “t”. The idea behind it is simple: keep the chest, back and stomach warm, and the rest of you feels warmer too, while your arms stay free to drive, cycle, carry a bag or reach for a pint.
A typical gilet has a zip or popper front, a stand collar or neat neckline, two hand pockets and a hem that finishes around the hips. Because it has no sleeves, it adds very little bulk under a coat, which is what makes it such a good layering piece.
Gilet vs body warmer vs vest
These words cause a lot of confusion, mostly because British and American English use them differently.
| Term | What it means |
|---|---|
| Gilet | The usual UK word for a sleeveless outer layer of any type: padded, quilted, fleece or knitted. |
| Body warmer | Another UK name for a gilet, most often used for padded or quilted styles. |
| Vest | In American English, a sleeveless outer layer (what the UK calls a gilet). In British English, a sleeveless undergarment worn beneath a shirt. |
| Waistcoat | A tailored, buttoned sleeveless garment worn with a suit. Smarter and closer fitting than a gilet. |
So if a shop describes a “puffer vest”, it is describing what most British men would call a padded gilet.
Types of gilet
Padded gilet
The warmest type, built like a sleeveless puffer jacket, with insulation held in stitched channels. The filling is either down or a synthetic alternative. Padded gilets are best as an outer layer on cold, dry days. Our guide to down jackets vs puffer jackets explains how the two kinds of filling compare.
Quilted gilet
Thinner and flatter than a padded gilet, with a light layer of wadding stitched in a diamond or box pattern. It has a smarter, more traditional look and slips easily under a coat or blazer. The Hyde Quilted Gilet is WARDLEY’s lightweight layering option.
Fleece gilet
Soft, breathable and casual. A fleece gilet is good for walking, weekends and working from home, and it makes a comfortable mid-layer under a waterproof. It gives less protection from the wind than a padded or quilted style when worn on its own.
Knitted gilet
Essentially a sleeveless zip or button jumper. It is the smartest of the four, worn over a shirt in place of a cardigan or under a jacket in place of a waistcoat. It adds a gentle layer of warmth rather than serious insulation.
What to look for when buying a gilet
- Weight. Decide whether it will mostly be an outer layer (go thicker) or a mid-layer under coats (go thinner and flatter).
- Collar. A stand collar keeps the neck warm and frames a shirt collar well. A collarless style layers more cleanly under tailoring.
- Fastening. A two-way zip lets you open the hem when sitting or driving. Poppers look more traditional.
- Pockets. Lined hand pockets are worth having in cold weather. An inside pocket is useful for a phone or wallet.
- Finish. A matt fabric reads smarter and is easier to wear with trousers and shirts. A shiny finish looks sportier.
- Colour. Navy, black, olive and charcoal go with almost everything. Stone and tan are good lighter options for spring.
How should a gilet fit?
It should sit close enough to layer under a coat without pulling across the chest. The armholes should not gape excessively. Beyond that, check the following:
- Chest: zip it up over a jumper. It should close without strain and lie flat, with no pulling at the zip.
- Armholes: high and neat. Large armholes let cold air in and make the gilet look too big.
- Length: it should cover your belt and end around the hips. If you wear it under a jacket, the gilet should be the shorter of the two.
- Shoulders: the edge should sit on the shoulder, not hang over it.
If you are between sizes, think about what goes underneath: take the smaller size for wearing over shirts and fine knits, the larger for chunky jumpers.
When should men wear a gilet?
Use one over a shirt or jumper in autumn, or under a heavier coat when winter temperatures drop. In practice, a gilet covers a lot of the British year:
- Spring and autumn: as the outer layer on mild, changeable days when a full coat is too warm.
- Winter: as hidden insulation under an overcoat or a waterproof jacket.
- Cool summer evenings: a light quilted or knitted style over a shirt.
- Commuting and travel: it keeps you warm on the platform and is easy to unzip on a heated train.
Most gilets are shower-resistant at best, so in steady rain wear a waterproof layer over the top. For the full approach, read how to layer menswear for a British winter, or see our layering pieces.
How to style a gilet
Three reliable combinations to start with:
- Quarter zip + gilet + chinos
- Oxford shirt + gilet + jeans
- Roll neck + gilet + overcoat
The first is a smart casual staple for the office or weekend. The second works with any plain or striped men’s shirt and dark jeans, finished with Chelsea boots. The third is the cold-weather option, with the gilet working as a hidden warm layer. Read our gilet outfit guide for more outfits and detail.
Mistakes to avoid
- Buying it too big. A loose gilet lets heat escape and looks boxy.
- A gilet longer than the coat over it. The hem should not show below your jacket.
- Too much bulk. A thick padded gilet under a slim coat will strain the coat. Use a thin quilted style for layering.
- Bare arms. A gilet over a short-sleeved T-shirt rarely looks right in the UK. Wear it over long sleeves.
Frequently asked questions
What is a gilet?
A gilet is a sleeveless jacket worn over a shirt or jumper to keep your core warm while leaving your arms free. It usually fastens with a zip or poppers and finishes at the hips. Men wear one either as a light outer layer in mild weather or as extra insulation under a coat.
What does gilet mean?
Gilet is a French word, adopted into British English to mean a sleeveless outer garment. It is pronounced with a soft “g” and a silent “t”, roughly “zhee-lay”. In everyday UK use it covers every style, from thick padded versions to thin quilted, fleece and knitted ones.
What is the difference between a gilet and a body warmer?
There is no real difference. Body warmer is simply another British name for a gilet, and the two are used interchangeably. If anything, body warmer tends to be used for thicker padded or quilted styles, while gilet is the broader term that also covers fleece and knitted versions.
Is a gilet the same as a vest?
In American English, yes: a vest is a sleeveless outer layer, so a “puffer vest” is a padded gilet. In British English a vest is an undergarment worn beneath a shirt, and the outer layer is called a gilet or body warmer. A tailored waistcoat is a separate, smarter garment.
How should a men’s gilet fit?
Close to the body without being tight. It should zip up comfortably over a jumper, lie flat across the chest, cover your belt and have neat armholes that do not gape. If you plan to wear it under a coat, choose a slimmer, thinner style so the coat still fits properly over it.
Can you wear a gilet in winter?
Yes. On dry, cold days a padded gilet over a thick jumper can be enough. In colder or wetter weather, wear a thinner gilet under an overcoat or waterproof jacket as an extra insulating layer. It adds warmth where you need it most without making the sleeves of your coat feel tight.
