Which Down Jacket Is Better And Warmer, Goose Down Or Duck Down?

It's the season to buy down jackets again, and the duck down and goose down are eye-catching. So, who is warmer, duck down or goose down?

Duck down: 40 days from growth to maturity. The rhombic nodes are larger and concentrated at the end of the small feather branches. Wearing it for a long time can easily drill down. Duck is an omnivorous animal with high oil content and heavy odor.

Goose down: From the growth stage to the mature stage for 100 days, the down buds are fuller and the down fibers are longer. The diamond joint is small and average, with a large spacing space and better fluffiness and resilience. At the same density, goose down has more heat locking holes, the plush flower is larger and less prone to burrowing. Goose is herbivores with low oil content and almost no odor.

In general, the warmth retention of 1.5 pieces of duck down is approximately equal to that of 1 piece of goose down. Therefore, in order to achieve the same warmth retention effect as a duck down jacket, more duck down filling is required.

Although, the warmth retention of a single duck down is not as good as a single goose down, but the warmth retention of down jackets also depends on the down content and filling amount. If the duck down jacket has a high down content and a large filling capacity, its warmth retention can completely exceed that of a goose down jacket with a lower filling capacity. After scientific washing and processing, down can effectively remove oil, making both goose down and duck down almost odorless.

Conclusion: The warmth retention of goose down may not necessarily be better than that of duck down, and it should be judged based on the amount of down filling. If the filling amount is the same, then goose down has better warmth retention than duck down.
