Every country has its own national headgear. The United States has the baseball cap, Britain is famous for the London bobby's helmet. Greece is associated with the fisherman's hat, while the beret is the symbol of France. The Israelis use the yarmulke and we usually see the Saudi Arabians in their white headdresses. Indian Sikhs wrap their heads in elaborate turbans while Russians warm their craniums with fur hats, which are of good use even at fifty Degree Celsius below zero. In Vietnam, the national chapeau is the non, or conical peasant hat. Along with the graceful silk ao dai, the non has become a sort of informal Vietnamese national symbol that is recognized worldwide.
