Goaltenders wear a different type of glove on each hand. While these gloves do offer the goaltender a measure of protection, their design is to aid the goaltender in performance of his duties. On the hand with which he carries his stick, often called the "stick hand," the goaltender wears a blocker with a large pad across the back of the forearm, usually extending just beyond the wrist. National Hockey League rules mandate that the blocking glove may be no wider than eight inches and no longer than fifteen. The goaltender uses this glove to stop shots.
