Trapper (ice hockey)
A trapper, also referred to as catch glove or simply glove, is a piece of equipment that an ice hockey goaltender wears on the non-dominant hand to assist in catching and stopping the puck.
Evolution
The trapper originally had the same shape as a baseball glove, but evolved into a highly specific piece of equipment that is designed specifically for catching the puck. Changes made over time include the addition of a "string mesh" in the pocket of the trapper and substantially more palm and wrist protection. The "cheater" portion of the glove covers the wrist, which evolved from gauntlet-like gloves from the 1920s.The trapper was introduced by goaltender Emile Francis while playing for the Chicago Black Hawks during the 1946-47 season.
