The same is the duvet, some are marked with duck down, some are marked with goose down, what is the difference between the two? Why do prices vary so much? Let's learn about several key indicators of down products with you, and then analyze according to these indicators to see the difference between goose down and duck down.
Key indicators of down products
Down content refers to the“fleece”content. In life, we can see it on the washing label of the purchased duvet or down jacket: the down content is 90% or 95% and so on.
Generally speaking, the higher the cashmere content, the lighter the weight and the better the warmth retention.
The amount of down filling does not determine the quality of down, but it can determine the value of a duvet or down jacket, because the amount of down filling represents the weight of down. In the case of the same cashmere content, the higher the cashmere filling, the more still air it can hold, and the better the warmth retention.
Loftiness is an important indicator to measure the warmth of down. The standard stipulates that the space occupied by one ounce (approximately equal to 28.35 grams) of down is 600 cubic inches (1 inch is approximately equal to 2.54 centimeters), which means that the filliness of the down is 600. Under a given down weight, the larger the space occupied, the better the loft and the higher the warmth retention.
Why is goose down more expensive than duck down?
Velvet is bigger
An important indicator to measure the quality of down is the bulkiness.
Compared with mature goose down and duck down, goose down has long down filaments, large down, higher fluffiness and high comfort, so the quality is better and the price is relatively expensive.
Generally, the growth cycle of geese is at least 100 days, while that of ducks is 40 days, so the down flowers of geese are fuller than those of ducks. The less the number of velvet flowers in 1 gram of velvet and the larger the individual velvet flowers, the higher the maturity of the velvet, and vice versa, the less mature the velvet and the shorter the growth time.

Small rhombus nodes are evenly distributed on the barbs of goose down, while the rhomboid nodes on duck down are larger and concentrated at the ends of small barbs, so goose down can produce a larger distance space and better fluffiness. Warmth is stronger.
Goose feathers have better curvature, are thinner and softer than duck feathers, have better elasticity and stronger resilience. The easiest way to test the resilience: Press the fluffy duvet/clothes once, and then loosen it, and if it rebounds quickly and returns to its original shape, it means that the down has good bulkiness.
