These HydroG Liquid-Filled No Bounce Street Hockey Balls are designed to have a reduced bounce to provide more realistic play. The balls are designed to play more like a puck and are filled with liquid to take the bounce out of them. The warm weather street hockey balls (orange) are meant for play in temperatures 60-degree Fahrenheit and warmer. You’ll get four HydroG Liquid-Filled No Bounce Street Hockey Balls and a re-closable mesh bag.
