During a fiercely cold winter, when you shudder in the wind, who cares about being stylish? All you need is warmth, the variety from light to heavy. Which down garments can provide you with? As living standards rise, more expensive garments filled with goose down, instead of duck down, have appeared in the market.

Goose or duck?

You may ask, what's the difference between these two? First, the down from mature geese is larger and thicker, which makes garments filled with goose down much warmer. Second, goose down is more flexible and fluffier than that of ducks. The last difference is key for people sensitive to smells: compared to duck down, goose down has no strange odor. Geese are often "vegetarians" and eat clean, while ducks are omnivorous, which could give their feathers and down a strong scent.

These are the advantages that account for the higher prices of garments made with goose down. However, duck down is still a good choice if you live in place where winter is windy, yet not that cold.

From the perspective of thermal insulation, White goose down is better than grey goose down, grey goose down is better than white duck down, white duck down is better than grey duck down, or their proportion is related to fluffy degree, the larger the filling ratio of the down, the warmer, the higher the fluffy, the warmer. The fluffiness of the filling is preferably above 700, the filling degree is more than 90%, and the filling amount is more than 200 grams, so that it can perfectly withstand the low temperature of minus 20 degrees.
