Kyahan were worn as padding underneath the samurai shin armour (suneate). Some types of kyahan could be covered with chain armour (kusari kyahan or kyahan suneate), these were worn by foot soldiers ashigaru or by samurai as protection. Kyahan were worn by ordinary travelers as protection from cold, insects and underbrush. Kyahan are often made of linen, but other materials such as cotton can be employed. Kyahan components depend on the season. When tying kyahan, the inner cords are shorter than the outer ones; it is also advisable that the cords are tied on the inner side of the legs instead of on the front or outer area. This helps prevent discomfort when the stiff suneate shin-guards are placed over the kyahan.
