CHINESE GREY DUCK DOWN

The Chinese partridge duck is the primary resource of grey duck down. Partridge ducks are widely bred in South China. It has brown and spotted plumages; that's why it has been called the 'spotty duck' as well. 

Grey duck down materials usually have decent insulation quality and less odor than white duck down because they are bred in the wild, and the breeding period is longer than white ducks.
