Yali men favour a long, thin koteka

"Men choose kotekas similar to ones worn by other men in their cultural group. For example, Yali men favour a long, thin koteka, which helps hold up the multiple rattan hoops worn around their waist. Men from Tiom wear a double gourd, held up with a strip of cloth, and use the space between the two gourds for carrying small items such as money and tobacco."

That's just how it was in my Junior High School!
