The primary equipment used in ice hockey includes a stick, puck, pads, and protective gear. The stick is essential for controlling the puck and making passes, while the puck is the object that players aim to maneuver into their opponent's goal. Players wear protective gear, including helmets, shoulder pads, and shin guards to minimize injury risks during the game. Goaltenders use specialized equipment, such as pads and gloves, to defend the goal from incoming shots. This gear is crucial for ensuring player safety and competitive play during matches.
