There is only one goalie on a lacrosse field. The goalie's job is to save the ball. The goalie uses a head specifically designed for saving shots. Goalie heads are taller and a lot wider than all the other positions' heads. Goalies also use a s goalie shaft (40" shaft). The goalie's pocket is also deeper than everyone else's pocket to keep the ball from bouncing out of the stick when saving a shot. The goalie does not wear any elbow pads to allow maximum mobility to save tough shots. All goalies are required to wear a throat guard and a chest protector and a protective cup.
