Bracer

A bracer (or arm-guard) is a strap or sheath, commonly made of leather, stone, or plastic that covers the inside of an archer's arm to protect it while shooting. Bracers protect the inside of the archer's forearm against injury by the string of the bow or the fletching of the arrow. They also prevent loose clothing from catching the bow string. They normally cover part of the forearm only, but chest-guards are sometimes worn, usually by female archers, and other areas have at times been protected. With some combinations of non-baggy clothing and bows with a larger distance between the bow and the string, the archer may not need to wear any bracer.
