It is often wondered what bird produces better down, a goose or a duck. While the answer may shock you, one is vastly superior to the other but both are still great. The IDFL, the world’s largest feather and down institute, states that goose generally tends to be a better product than duck. First off, goose clusters are typically much larger than duck clusters and come from older and larger birds. What this produces is a higher amount of fill power, making the down more durable and resilient.
But, goose down also plays a helping hand in odor control. Geese do not have much of a diet, mostly eating grass, and as such, it is easier for manufacturers to control the odor from the down. Meanwhile, ducks have a diverse diet and the odor becomes more of an issue. That being said, do not think that duck down is incompetent; it is just that goose down is superior.
