Boxer briefs are a popular style of men’s underwear known for their snug fit and comfortable support. But what are they called in the UK?
In the UK, boxer briefs1 are typically called “trunks2” or “boxer trunks.” While the term “boxer briefs” is also understood, “trunks” is more commonly used to describe the shorter, fitted style that combines the features of boxers and briefs. The name variation is influenced by regional language differences and fashion terminology.
Let’s explore the history of this versatile underwear style, why the terminology varies, and how to choose the right fit for comfort and support.

Why are they called trunks in the UK?
The term “trunks” has historical roots and is widely used in British fashion.
In the UK, “trunks” originally referred to shorter, snug-fitting swimwear worn by men. This name was later adopted for the fitted underwear style that provides the same streamlined silhouette. Trunks are typically shorter in the leg than traditional boxer briefs but longer than briefs, offering a comfortable and supportive fit.
This naming convention reflects the influence of swimwear fashion on men’s underwear styles.
How do trunks differ from boxer briefs?
While similar, trunks and boxer briefs have subtle differences in fit and style.
Trunks are generally shorter in the leg compared to boxer briefs, which offer longer coverage. Boxer briefs tend to reach mid-thigh, while trunks have a more squared-off appearance with a shorter inseam. Both styles provide a snug fit and full support but differ in length and silhouette.
Choosing between them depends on personal preference and comfort.
| Style | Length | Fit and Support |
|---|---|---|
| Boxer Briefs | Mid-thigh length | Snug fit, full coverage |
| Trunks | Shorter inseam, square cut | Snug fit, moderate coverage |
| Briefs | High cut on the thigh | Snug fit, minimal coverage |
| Boxers | Loose and longer | Relaxed fit, minimal support |
