Swim trunks are lightweight, quick-drying shorts designed for swimming or casual water activities. Typically made from materials like polyester or nylon, they feature mesh linings for comfort and water drainage. Unlike board shorts or jammers, swim trunks are shorter and looser, offering more freedom of movement both in and out of the water.

In 2025, many brands are reimagining classic swim trunks with features such as four-way stretch, UPF sun protection, and water-repellent coatings, making them ideal for both swimming and lounging.

  • Board Shorts: Longer and more fitted, often without inner mesh. Ideal for surfing or beach sports.

  • Square-Cut Trunks: Shorter and more form-fitting, often chosen by professional swimmers or those who prefer a sleek look.

  • Hybrid Swim Shorts: Designed to function as both swimwear and casual wear, suitable for travel or beachside dining.

Each style caters to a different level of activity, personal comfort, and aesthetic preference.
