A swimming cap is a close-fitting piece of headgear made from rubber, silicone, or latex that is worn by swimmers to help reduce water resistance, protect hair from chlorine, and keep hair out of the face during swimming. It typically covers the top, sides, and back of the head, leaving the face open, and is designed to fit snugly without slipping off. Swimming caps come in various colors, styles, and sizes, often featuring smooth, shiny finishes for minimal drag. Some have textured designs for added grip or comfort, while others may include features like ear protection or UV resistance. They are commonly used in competitive swimming and recreational swimming alike
