What is a "swimming cap"?
A swimming cap is a tight-fitting headgear that is typically made of rubber, latex, silicone, or lycra, worn by swimmers to protect their hair from chlorine and other chemicals in the pool, and to reduce drag in the water. It comes in various colors, styles, and sizes to fit different head sizes and preferences. A swimming cap is an essential gear for competitive swimmers, as it helps to streamline their heads and minimize resistance, which can improve their speed and performance in the water. It is also used by recreational swimmers, especially those with long hair, to keep their hair out of their face and to prevent it from clogging the pool filters.
