If piña fabric (made of pineapple leaf fibers) and jusi fabric (made of silk) got together and had a baby, the baby would be cocoon fabric. That's not quite accurate, but it sounded cool, and it's kind of close. Cocoon fabric is made of silk, but it is woven in a way to resemble the look of piña fabric.
Cocoon fabric is smooth to the touch, translucent and is unlined. Cocoon is about as durable as jusi since they are both made of silk, and cocoon's weave is similar to that of piña silk.
Cocoon barongs are considered formal wear for men, and they are about as formal as wearing piña silk barongs since they look like them.
