This adult swimming cap made of polyester is ideal for all swimming enthusiasts. With its green color, it offers not only style but also functionality. Its purpose is to keep the hair contained close to the head, preventing hair from falling into the water. Additionally, it reduces resistance, making it easier for the swimmer to move. Particularly in winter, it helps retain heat in the head, although it does not keep the hair dry. However, it protects the hair from chlorinated water, contributing to their health.
