A wristband is a band worn around the wrist, serving various functional and decorative purposes, such as a wristwatch strap, a sweat absorber for athletes, a security pass for events, a medical identification for patients, or a tool to provide support and stability for lifting heavy weights in the gym. These bands are made from different materials, including fabric, plastic, silicone, and leather, and can also be used to show support for a cause or idea.
