Swimming cap for adults made of silicone. Its purpose is to keep the hair confined close to the head and to prevent hair from falling into the water. The cap creates less resistance and facilitates the swimmer's propulsion. In winter, it helps keep the head warm.

The cap does not keep the hair dry; however, it limits contact with water and protects the hair from chlorinated water. Silicone caps have the advantage of being elastic and secure. They are affordable and do not require special care after each workout.
