Cloth worn over armour or padding by a horse. (Prestwich, Michael. Armies and Warfare in the Middle Ages: The English Experience, 348) Textile or leather covering for a horse, reaching to the fetlocks and usually entirely covering the animal except for openings for eyes and muzzle. (Wise, Terence. Medieval Warfare, 251)
An all-enveloping textile cover for a horse, reaching to the fetlocks and leaving only the eyes, ears, and nose uncovered. It often displayed the rider's arms.
Worn on the left hand (for right-handed goaltenders), and similar in shape to a fielder's mitt in baseball, the trapper is usually the goaltender's strong point. The trapper should be kept at knee height, just above the leg pad, and should be open at all times. To stop play with the trapper, the goaltender catches the puck, then brings the trapper in towards his/her chest to prevent an opponent from knocking the puck away. Terry Sawchuk shows an example of a trapper save.
