A clear guide to the main types of jackets for men and women, from blazers and bombers to parkas and trench coats, with the fabric and weather each one suits.

## Quick answer

> Most types of jackets fall into four families. Tailored jackets (blazer, sport coat) dress an outfit up. Casual jackets (denim, bomber, Harrington, leather, chore coat) cover everyday layering. Weather jackets (rain shell, windbreaker, trench) block wind and rain. Cold weather jackets (puffer, parka, peacoat, overcoat) insulate. Choose by the job first, then by fabric and fit.

Bomber, Harrington, chore coat, shacket, anorak: on a shop page the names blur together. Meanwhile a closet with three jackets in it can still offer nothing right for a forecast of 55°F (13°C) and drizzle. Knowing the main types of jackets is less about memorizing names and more about knowing what each one was built to do.

Nearly every jacket began as a uniform or a piece of workwear: flight crews, sailors, miners, soldiers in the trenches. The original job still shapes the fabric, the length and the details, and it tells you where the jacket fits in your life today. Grouping jackets by that job, rather than by name, is the quickest way to see which ones you need and which you already have covered.

## Tailored jackets: blazer, sport coat and suit jacket

Tailored jackets have a structured shoulder, lapels, a buttoned front and usually a lining. A suit jacket is cut from the same cloth as its trousers and is meant to be worn with them. A blazer is a standalone jacket, traditionally in solid navy with metal or contrasting buttons. A sport coat is the more casual cousin, often in a textured or patterned cloth such as tweed, herringbone or a check, and it is meant to be worn with trousers that do not match.

These are the jackets that move an outfit into [smart casual](https://snaza.app/journal/smart-casual-dress-code/) territory. A navy blazer over a knit polo and chinos works for most offices and dinners; a tweed sport coat with jeans and boots reads relaxed but deliberate. For women, a blazer in wool, linen or a crepe with a little stretch plays the same role over a dress, a T shirt or wide trousers. Fit is what makes or breaks them: the shoulder seam should end at your shoulder, and the sleeve should show a little shirt cuff, as our guide to [how a suit should fit](https://snaza.app/journal/how-a-suit-should-fit/) explains.

## Casual jackets for everyday layering

The denim jacket began as workwear. Levi Strauss made the first recorded American denim jacket around 1880 for miners and laborers, and the 1962 Type III, the trucker jacket with pointed chest pockets and a tapered body, is the shape most people picture today. It sits at the waist and layers over a hoodie in spring or under a heavier coat in winter. If you wear it with jeans, choose a clearly different wash so the two pieces do not look like a mismatched suit; our guide to [what denim is](https://snaza.app/journal/what-is-denim/) explains washes and weights.

The bomber jacket comes from military flight gear. The leather A 2 was standard issue in the 1930s, and the nylon MA 1, usually sage green with a bright orange lining meant to be turned out for visibility in an emergency, is the version sold everywhere now. Its defining details are the ribbed collar, cuffs and hem, which trap warmth and give it a blousy shape above the belt. A bomber works for anyone: with jeans and sneakers, over a dress, or in suede or wool for a smarter look.

The Harrington jacket is lighter still: a waist length cotton or poly cotton jacket with a stand collar, a zip front and, traditionally, a tartan lining. It began as a golf jacket made by Baracuta in the 1930s and took its nickname from a character in the 1960s television series Peyton Place. Alongside it sit the chore coat, a boxy cotton canvas or twill work jacket with patch pockets, and the leather biker or moto jacket with an asymmetric zip, which suits both men and women and softens with years of wear. Care for that last one is covered in [how to clean a leather jacket](https://snaza.app/journal/how-to-clean-a-leather-jacket/).

The shirt jacket, often called a shacket, is exactly what it sounds like: a heavy flannel, wool or corduroy shirt cut roomy enough to wear over a sweater. It is the most useful piece for the weeks when a sweater alone is too little and a coat is too much.

## Jackets for wind and rain

A rain jacket, or shell, has no insulation; its job is to keep water out. Hardshells use a waterproof, breathable membrane with taped seams and are the right choice for real rain. Softshells are stretchier and more comfortable but only water resistant, which is fine for showers and wind, not a long walk in a downpour. Most rain jackets have a hood, and when you shop for a jacket with a hood, check that it has an adjustable brim and back strap so it turns with your head instead of blocking your view.

A windbreaker is a thin nylon or polyester jacket that stops wind and light drizzle and folds into a pocket. An anorak is the pullover version, often with a half zip and a large front pouch. The trench coat is the elegant answer to the same problem. Burberry and Aquascutum both claim it, and it was worn by British officers in the First World War; the classic version is a double breasted gabardine coat with a belt, storm flaps and buckled cuff straps. It is a rain and wind coat, not a winter coat, and it layers over a suit or a sweater equally well.

## Cold weather jackets and long coats

A puffer jacket is stitched into baffles filled with down or synthetic insulation. Down gives the most warmth for its weight and packs small, but it clumps and loses much of its warmth when soaked; synthetic fill keeps working when damp and is easier to wash. A parka adds length, usually to mid thigh, plus a hood and a weatherproof outer shell, so it combines rain protection with insulation. For the coldest days a parka is the most practical single coat you can own, and our guide to [washing a down jacket](https://snaza.app/journal/how-to-wash-a-down-jacket/) keeps it lofty.

Wool coats take a different route to warmth: dense cloth rather than trapped air. The peacoat, originally a sailor's coat of heavy navy wool, is short and double breasted with broad lapels and two rows of buttons. Longer styles include the overcoat, which reaches the knee and is cut to fit over a suit jacket; the car coat, which stops at mid thigh; the camel coat; and for women the wrap coat, tied with a belt instead of buttoned. Among long coats for both men and women, a plain knee length wool coat in navy, charcoal or camel is the most versatile over tailoring. Shearling, sheepskin with the wool left on as a lining, is the warmest of the traditional options.

Fleece and quilted jackets sit between these families. A zip fleece is warm and light for its bulk but lets wind straight through, so it works best as a mid layer under a shell. A quilted jacket, flat stitched with thin insulation, is a good town jacket in autumn and fits under a larger coat when temperatures drop.

## Types of jacket material and what they do

Wool is warm, naturally water repellent in light rain and resists odor, which is why it dominates coats and tailored jackets. Cotton twill, canvas and corduroy are breathable and tough but soak up rain and dry slowly, so they suit dry cool days. Denim is a cotton twill too, heavier and more hard wearing. Leather and suede block wind almost completely; smooth leather handles a little rain, suede does not.

Polyester and nylon are the workhorses of outdoor jackets. Polyester jacket fabric is light, quick drying and holds its shape; nylon is stronger for its weight and shows up in windbreakers and shells. Both are usually given a water repellent finish, and on waterproof jackets they are bonded to a membrane. There is no single best fabric for jackets, only the best fabric for a climate: for winter jacket fabric types in wet cold, look for a weatherproof synthetic shell over insulation; in dry cold, a dense wool coat is hard to beat. Our comparison of [polyester and cotton](https://snaza.app/journal/polyester-vs-cotton/) goes deeper on how synthetics behave.

**Jacket fabrics compared**

| Material | What it does well | Best for |
| --- | --- | --- |
| Wool | Warm, sheds light rain, resists odor | Coats and tailored jackets |
| Cotton twill, canvas, corduroy | Breathable and tough, but soaks up rain | Dry, cool days |
| Denim | Heavy, hard wearing cotton twill | Everyday casual jackets |
| Smooth leather | Blocks wind, handles a little rain | Biker and moto jackets |
| Suede | Blocks wind | Dry days only |
| Polyester | Light, quick drying, holds its shape | Outdoor jackets |
| Nylon | Strong for its weight | Windbreakers and shells |

## How many jackets you actually need

Most people in the United States and Canada can cover the year with three or four jackets: one casual jacket for mild days (denim, bomber or Harrington), one tailored jacket for work and dinners, one weatherproof shell or trench, and one warm coat suited to your winters. In a mild climate the warm coat can be a wool peacoat; where winters bring snow and deep cold, it should be an insulated parka.

Before buying another, try the jackets you own over your thickest sweater and your lightest shirt. A jacket that only works over a T shirt is a spring jacket, whatever the label says. Our guide to [dressing for 50 degree weather](https://snaza.app/journal/what-to-wear-in-50-degree-weather/) shows how each type layers as the temperature drops.

**Worth remembering**

1. Choose a jacket by the job it has to do first, then by fabric and fit.
2. Down gives the most warmth for its weight but loses much of it when soaked, while synthetic fill keeps working damp.
3. A zip fleece lets wind straight through, so it works best as a mid layer under a shell.
4. A jacket that only works over a T shirt is a spring jacket, whatever the label says.

## Questions people ask

### How many types of jackets are there?

There is no fixed number, because new names appear every season. Almost all of them fit into four groups: tailored jackets, casual jackets, weather shells and insulated cold weather coats. Knowing which group a jacket belongs to tells you more than its name.

### What is the difference between a jacket and a coat?

In everyday American use, a jacket is usually hip length or shorter and a coat reaches at least mid thigh. Coats are also more often cut to be worn over other layers, including a suit jacket. The words overlap, and plenty of garments, such as the peacoat, carry both names.

### What is the difference between a blazer and a sport coat?

A blazer is traditionally a solid color jacket, most often navy, with metal or contrasting buttons. A sport coat is usually made from a textured or patterned cloth such as tweed or a check. Both are worn with trousers that do not match them, unlike a suit jacket.

### Are the jackets for men and women really different?

The core types are the same for everyone; the differences lie in cut and button side. Women's versions of blazers, trench coats and peacoats are usually more shaped through the waist and button right over left, while men's button left over right. Many casual jackets, such as bombers and denim jackets, are sold in nearly identical versions.
