Gauntlets – a glove; specifically in medieval armor, the defensive covering of the hand

“We had not long to wait. There was a clanking of chains and deep groans. Then out of the library stepped an old-time knight, a short length of chain tracing behind one foot. His hands were encased in chain gloves, with gauntlets attached. His face was pale and luminous.”
