In ice hockey, the goaltender is the player responsible for preventing the hockey puck from entering their team's net, thus preventing the opposing team from scoring. The goaltender mostly plays in or near the area in front of the net called the goal crease. Goaltenders tend to stay at or beyond the top of the crease to cut down on the angle of shots. In the modern age of goaltending there are two common styles, butterfly and hybrid. Because of the power of shots, the goaltender wears special equipment to protect the body from direct impact.
