Swimming cap for adults made of silicone. Its purpose is to keep the hair confined close to the head and to prevent strands from falling into the water. The cap creates less resistance and makes the swimmer's propulsion easier.

In winter, it helps keep the head warm. The cap does not keep the hair dry; however, it minimizes contact with the water and protects the hair from chlorine.

Silicone caps have the advantage of being flexible and secure. They are economical and do not require special care after each training session.
