Phu Tho is land of palm trees so the development of conical hat occupation is inevitable. However, for many last years, the hat production of the province has been in small-scale. Unlike conical hats of Chuong village in Ha Tay province or Hue�s city lata-nia leaf hats, Phu Tho conical hats characterize by simplicity, harmonious lines, durableness and reasonable price.

Phu Tho province has many villages engaging to hat production occupation. The villages producing on large scale are Son Nga, Sai Nga, Thanh Nga, Dong Phu and Dong Khe. Son Nga is the longest standing craft village but now the village diminishes its production due to low economic effect. 

In recent decade, Sai Nga is biggest conical hat production in the region. The village has become a workshop bustling all day with production processes of leaf cutting, ironing, designing and hat sewing.

A good hat is a hat with beautiful and even sewing lines and flat surface. A verse of poem, or a picture is placed in between two layers of thin leaves. 

Simplicity, white and long-wearing is Song Thao conical hat. 

Those who travel here and there, visit Song Thao wearing beautiful hats.
