A tennis overgrip is a thin, extra layer of material that wraps around the handle of a tennis racket. It provides added comfort, enhances grip, and absorbs sweat, helping players maintain control and prevent slippage during play. Overgrips are commonly used to refresh the feel of a racket's original grip or to customize the handle's texture and thickness. https://letsgotennis.com/tennis-products/best-tennis-overgrip/
