Board shorts vs. swim trunks: what’s the difference?

Swim trunks are leisure apparel for recreational beach, lake, or poolside use, while board shorts are purpose-built for active performance in a wide range of water-based activities.

For some, board shorts are a subcategory of swim trunks. For purposes of this article, we’ll treat them as separate categories of men’s swimwear, since they serve quite different functions.

We'll dive into the similarities and differences between swim trunks and board shorts so you can pick a style that's right for you.

About board shorts

Japanese-Hawaiian tailor Minouri Nii developed the modern board short in the late 1940s on Oahu's Westside. These shorts support almost all active water-based pursuits. They are a preferred technical choice for water sports such as surfing, bodysurfing, diving, swimming, and sailing.

People love board shorts because of their fixed waist design—a panel of reinforced, two-ply rigid fabric with a front drawcord closure. This sturdy, fixed waist secures the shorts to the hips throughout different activities.

The shorts' fabric composition provides ample freedom of movement and a comfortable fit. The combination of a secure waistband and flexible material gives you a chance to engage in watersports with confidence and ease.

About swim trunks

Swim trunks blend comfort and style. They are shorter than board shorts, which results in a more streamlined silhouette. The elastic waistband provides a secure fit. Most men find them easy to wear, as they provide freedom of movement during swims, beach games, or pool lounging.

Quick-dry materials give smooth transitions from water to land, so you can stay comfortable while swimming and sunbathing. Many styles include built-in mesh liners for additional support and comfort, which reduces chafing. Practical pockets let users keep essentials close.
