It protects the archer's forearm against injury by accidental whipping from the bowstring or the fletching of the arrow while shooting, and also prevents the loose sleeve from catching the bowstring. They normally only cover part of the forearm, but full-length bracers extending to the upper arm are also available, and other areas
