Glove (ice hockey)

There are three types of gloves worn by ice hockey players. Skaters wear similar gloves on each hand, while goaltenders wear gloves of different types on each hand.
Types of gloves.
Skaters' gloves.
Skaters' gloves are designed to protect the players' hands from pucks, sticks, and skates. They do not play any role in the performance or play of the game. 
Goaltender's glove.
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.
On the other hand, often called the "glove hand", the goaltender wears a catching glove, similar to a baseball glove. NHL rules limit the perimeter of the catching glove to forty-five inches and the widest part of the glove may not exceed eighteen inches.
