These swim shorts are super easy to use. Just put them on like you would any regular shorts and head to the pool or beach. When it comes to maintenance, you can simply throw them in the washing machine. But make sure to follow the standard machine - wash instructions to keep the colors bright and the fabric in good shape. As for sizing, they're designed to fit all shapes and sizes, and the adjustable side - fasteners allow you to customize the fit. Don't worry about rough handling; they're made from 100% recycled polyester, so they're durable. Just avoid sharp objects that could tear the fabric. Enjoy your swim!
