The larger the down feathers are, the more difficult it is to purify because the filaments are long and the feathers are tightly entangled with each other; the general processing factory can only extract the down to 86~88. And to refine to a higher down content (90~95 down), you need a very professional down manufacturer to do it.

4-6cm white goose feather is widely used in different fields. It has the characteristics of large down, small feather handle, light weight, high filling force, tasteless, and high warmth retention.
