Most women's swim trunks are made from polyester- or nylon-based fabrics blended with spandex (for stretch). Many listings use polyester/spandex or nylon/spandex blends, and some specifically note recycled nylon options.
Built-in coverage varies: common options include a panty-style inner lining, mesh liners, or soft boxer-style liners. Several listings describe trunks with a built-in panty or liner for added modesty and support.
Most trunks are pull-on with elastic waistbands; many also include adjustable features such as drawstrings, inner drawcords, or adjustable waistbands for a more secure, customizable fit.
Many trunks include side pockets; some also offer zippered side pockets, small waistband pockets, or hidden slip pockets for carrying small essentials.
Care instructions vary by item: some trunks are machine washable and can be tumble dried, while others recommend hand washing and line-drying or laying flat to dry. Check the specific product label for exact care guidance.
Listings describe trunks suitable for swimming and a range of water and beach activities—surfing, kayaking, paddleboarding, water skiing—plus beach walks, workouts, and casual wear.
Common details include plain hems, dolphin hems, and side splits or V-slits designed to increase mobility and create different silhouettes.
