The swimming cap is specifically designed for children from polyester, offering comfort and practicality while swimming. Its colorful design adds joy and vibrancy to the swimmer's experience, making it popular among young swimmers. Its main purpose is to keep the hair close to the head, thus limiting hair loss in the water and reducing drag while swimming. Additionally, the cap helps maintain the temperature of the head, especially during the winter months, although it does not keep the hair dry, it provides protection from chlorinated water.
