Hungarian down is by far the most widely know and often professed to be the best down by many duvet manufacturers world wide.
The Hungarian farmers know how to get the best out of their geese, they allow the birds to develop to a more mature age and are fed a higher protein diet than that in the orient, which in turn means that the coat of the geese is thicker, producing a better fill power (loft) and the better diet ensures a longer lasting life span.
