For men and women who suffer from being in the saddle for so many hours, there is a choice between the "kerjava" and the "takht-i-rawan." The kerjava, in its best appearance, takes the form of two very small gypsy tents made of light bands of wood, the top bent circular, and covered with shawls or carpets. In each of these tents a man or woman sits after the kerjavas have been slung, like panniers, across the saddle of a strong mule. In the kerjava one must sit cross-legged, or with one's feet hanging out.
