The swimming cap for children is made of polyester materials, offering a comfortable fit and ease during water activities. Its purpose is to keep the hair confined close to the head, preventing hair from falling into the water, while also reducing resistance and facilitating the swimmer's propulsion. Additionally, during the winter period, it helps maintain the temperature of the head. Although the cap does not keep the hair dry, it limits contact with the water and protects the hair from the harmful effects of chlorinated water.
