1. Which Is Warmer: Duck Down or Goose Down?
By now you’ve seen that the choice between duck down or goose down depends on your preferences and budget. But which is warmer — duck down or goose down? Goose down is warmer! As the table shows, there is a small difference in insulation value. Down naturally has a high insulating capacity, meaning you need less filling to stay warm.
Because goose down consists of larger and stronger down clusters than duck down or duck feathers, even less filling is needed to achieve the same level of warmth. A goose-down duvet is therefore extra light while still wonderfully warm.
2. Moisture Absorption in Different Types of Down
Another difference is moisture absorption. If you’re asking “what’s better, duck down or goose down?” in this area, goose down scores slightly higher. This is related to the structure of the down — more on that in point 4.
Why does moisture absorption matter? During the night we lose a lot of moisture, through sweating but also through breathing. A moisture-absorbing duvet and pillow are essential for a good night’s sleep. Down is always a great choice because it absorbs moisture extremely well — but goose down does it just a little better.
