Types of Coats and Jackets Explained: Trench, Peacoat, Parka, Bomber and More
A clear guide to the main types of coats and jackets, including trench, peacoat, overcoat, parka, bomber, duffle and puffer, with advice on when to wear each.
Key takeaways
- Coats are chosen by weather and formality: wool for smart cold wear, shells for rain, and insulated styles for deep cold.
- Length and cut change how formal a coat looks.
- A neutral wool overcoat and a rain-ready jacket cover most needs.
Coat names can be confusing, because brands use them loosely. The classic types below each began with a practical purpose and are still defined by their shape, fabric and details.
The main coat types
| Coat | Defining features | Best for |
|---|---|---|
| Trench coat | Belted, double-breasted, usually water-resistant cotton gabardine, with storm flaps. Associated with military use in the First World War | Mild, rainy weather and smart casual wear |
| Peacoat | Short, double-breasted wool coat with wide lapels. Based on naval clothing | Cold weather, smart casual |
| Overcoat | Knee-length, tailored wool coat, single or double-breasted | Formal and business wear in winter |
| Duffle coat | Hooded wool coat with toggle fastenings. Named after the Belgian town of Duffel | Casual cold weather |
| Parka | Hooded, insulated and often fur or faux-fur trimmed. Derives from garments worn in Arctic regions | Deep cold and wet weather |
| Puffer | Quilted jacket with insulating filling in sewn chambers | Cold weather, travel and outdoor use |
| Bomber | Short jacket with ribbed cuffs and hem. Originated as flight jackets | Casual wear in mild cold |
| Leather jacket | Close-cut jacket in leather, often with a zip front | Casual wear and mild weather |
Length and formality
Longer coats look more formal. A knee-length overcoat suits tailoring and a suit, while a hip-length jacket suits casual outfits and jeans. A coat should fit over your usual layers without pulling at the shoulders or back. See our guide on how clothes should fit for the shoulder and sleeve checkpoints.
Fabrics to look for
- Wool and wool blends: warm, breathable and smart. Read the fibre mix and our wool guide.
- Cotton gabardine: tightly woven, lightweight and naturally water-resistant.
- Technical shells: synthetic fabrics designed for rain and wind. See our guide to waterproof and water-resistant jackets.
- Down or synthetic fill: for puffers and parkas, as covered in our puffer jacket guide.
How to choose
- For work and formal wear, choose a plain wool overcoat in navy, charcoal or camel.
- For unpredictable weather, choose a trench or a technical shell.
- For deep winter, choose an insulated parka or a down puffer.
- For weekends, a bomber, peacoat or duffle works with jeans and boots.
Caring for your coat
Brush wool coats regularly, hang them on broad hangers, and air them between wears. Wool coats usually need cleaning only once a season. Check the label for each coat, because fabrics and linings differ.
