Jusi barongs are made of silk. The fabric is smooth to the touch, translucent and is unlined. Jusi is thinner, has a tighter weave and is more durable when compared to piña silk.
Jusi barongs are considered formal wear for men, but they are less formal than piña silk barongs. Wearing a jusi barong is like wearing a suit, dress shirt and tie, as opposed to wearing a piña silk barong, which is like wearing a tuxedo.
