    Abstract: A goaltender device features a cord; a wrist strap attached or attachable to a first end of the cord; and a clip attached or attachable to a second end of the cord for selective attachment of a goalie glove thereto. During use, the goaltender temporarily removes their goalie glove to expose the glove hand for use in a two-handed grip on a goal stick, during which the goalie glove hangs on the cord from said glove arm of the goaltender. The goaltender then uses a thrusting movement of the glove hand arm to pulling the glove back up to the glove hand via the cord.
