Jusi barongs are made of silk. The fabric is smooth to the touch, translucent and is unlined. Jusi is thin, has a tight weave and is more durable than piña silk.
Jusi barongs are considered formal wear for men, but they are less formal than piña silk and cocoon barongs. Wearing a jusi barong is like wearing a suit, as opposed to wearing a piña silk or cocoon barong, which is like wearing a tuxedo.
