Are you inclined to prefer white duck down over grey duck down when buying down products? This is not true. The only difference between grey duck down and white duck down is the color.
Generally, the quality of down depends not on its color, but on its density and fineness. Grey duck down and white duck down have little difference from this perspective.
In most cases, down jackets and down comforters are filled with grey duck down for dark-colored fabrics, and white duck down for light-colored fabrics. It’s just for color matching. As long as the down content and fill power are the same, there isn’t much difference in bulkiness and comfort between white duck down and grey duck down.
The contrast of white down and grey down in color.
In terms of varieties, down feathers can be divided into white goose down, grey goose down, white duck down, and grey duck down. The price of goose down is higher than that of duck down, and the price of white down is higher than that of grey down for the same down content.
Compared to white duck down, white goose down has a better overall quality under the same conditions. White down and grey down are functionally identical, only their color differs. There are many people who believe that white down is better because of their emotional attachment to the color white.

More than a dozen indicators were found to be similar between white duck down and grey duck down, including weight, grade, bulkiness, comfort, cleanliness, and antibacterial performance. Therefore, it does not matter what color the down is, as long as the craftsmanship is done properly.
Why is white duck down more expensive than grey duck down?
Grey duck down is the same quality as white duck down, it’s just a different color. Is there a reason why their prices differ so much?
As a result of its light color, white duck down suits many fabrics, while grey duck down suits dark fabrics. According to consumers, white duck down is preferred subjectively, so there is a much greater demand for white duck down, which leads to a higher price.
Which is warmer, white duck down or grey duck down?
There is no heat generated by down feathers themselves. By blocking cold air from outside, down products retain warmth. You can keep warm with a down feather because it is insulated, preventing the loss of body heat. Down products retain warmth based on their down content and fill power, but not on their color. Duck down of the same grade is almost as thermally insulating as white duck down.
Are down products better the more down they contain? No, the answer is no. The filler will lose heat through conduction as it becomes denser, so it will no longer be able to keep you warm.
In addition to stating whether a down jacket uses white duck down or grey duck down, the label will also list the content, such as 70%, 80%, and so on. High-quality down jackets contain more than 90% down, but the more down the better. If you see a jacket with 100% duck down, it is probably not real. The sorting machine mixes feathers with down, which is inevitable. It is only possible to pick 100% duck down by hand. As a result, the time and labor costs will increase, and the price of duck down will increase accordingly.
It is not only the amount of down that determines how warm down is, but also the fill power that affects how warm it is.
Down products are warm due to the fill power of duck down, which increases the effect of air thermal insulation. Duck down contains more insulating air, so the higher the fill power, the less heat will be lost, and the warmer the product will be.
White duck down is generally warmer than grey duck down. Duck down’s quality lies not in its color, but in its down content and fill power.
Which one should we choose white duck down and grey duck down?
It does not matter if it is white duck down or grey duck down, the difference in color does not affect the quality.
Most of the time, we see down jackets and down comforters on the market. Grey duck down is most commonly used in dark fabrics, and white duck down is most commonly used in light fabrics. If white duck down and grey duck down have the same down content, down filling quantity, and fill power, they will provide the same comfort and warmth.
Ducks use duck down to keep warm. Do white ducks have a greater resistance to cold than black ducks?
Is it a quality problem that there are other colors of down in the white duck down?
Pure white down is preferred emotionally by many consumers, and other colors in the white down are unacceptable. There is a misunderstanding here! When duck down is washed, it will always be mixed with white, grey, and brown down. Be cautious if you see down products with no other colors of down because they may have been chemically bleached. The ingredients in such down are harmful to your health.
Color has nothing to do with the quality of down products filled with duck down. There is generally a belief that white down is more popular because it is easy to cover with light-colored fabrics, giving you a larger selection of appearance colors. There will be a lot less selection of gray duck down since it can only be used on dark fabrics.
White duck down and grey duck down both have the same amount of down and fill power, so their only difference is their color, but their warmth and comfort are the same.
