They are typically made from quick-drying materials like polyester or nylon and come in various styles, including board shorts and fitted designs. Swim trunks are often worn at pools, beaches, and during water sports. These garments usually feature an elastic waistband and may include a drawstring for a secure fit. Swim trunks are available in a wide range of colors and patterns, making them a popular choice for summer activities. They are often paired with flip-flops or rash guards for added comfort and sun protection.
