This is a type of silk weave done with spun silk threads. Pongee's surface is not as smooth or glossy as that of silk woven with raw silk threads, and it has a plainer, more casual look. Traditionally it was often woven in striped or kasuri patterns, but recently it is possible to produce a wide range of gradations and other designs using various types of dyed threads.

Pongee fabric is highly suitable for kimonos and obi (kimono sashes) because of its strong, supple texture.
