The goalie blocker is a rectangular piece of equipment worn by ice and roller hockey goaltenders. It is generally worn on the dominant hand (right hand for right-handed players).

The blocker is a close-fitting glove augmented on the back of the hand, wrist and part of the forearm by a rectangular "block" of padding and fabric (leather or synthetic). Goaltenders hold their stick in that hand and use the padded rectangle to block shots -- bouncing them away from the net, as opposed to holding them in the catching glove. Experienced goalies can "steer" the shot by angling the blocker as the puck strikes. The padding also serves to protect the hand and lower forearm of the goaltender.
