The riders, or chopendoz, wear high leather boots, a quilted (padded) jacket over a long chapan and a fur hat traditionally made of fox or wolf skin. They carry short whips which are made up of a handle attached to a piece of wood about a foot long encased in leather. The chopendoz not only whip their horses but also the other riders – especially the one carrying the boz. In olden days the whips were different and were made up of a handle attached to thongs tied to balls of lead (a bit like a cat-o-nine-tails used in the British Navy in the days of sailing ships). The chopendoz of old also carried a knife and sometimes stabbed an opponent’s horse or even it’s rider when attempting to steal the boz. It was not unknown for chopendoz to be killed in a fiercely competitive game. Nowadays it is a little more civilised (but not much) and riders still get hurt, but they are a tough breed of men. Often a chopendoz will get one arm or leg broken and mount their horses as soon as the fractures are bandaged. An injury does not stop the horsemen from continuing the game.
