Fill Power, Down content，Fill Weight, and Product Weight are three key measurements to help understand the quality and warmth of our Down products.
Fill Power refers to the loft of the down used in the item or how voluminous (puffy) that down is. Loft is another way of measuring how many cubic inches of space one ounce of that down fill takes up. The loftier the down, the more space there is for air to get trapped, and therefore, the more insulated it is.An important factor that determines the filling power is the content of down. The higher the down content, the more fluffy the filling is.
Down content:We usually see different content standards such as 95%\\90%\\50%\\30%, which refer to the proportion of pure down and feathers, feather silk and other impurities in the raw materials. For example, 95% of white goose down contains only 5% impurities and the rest is pure down. Of course, if it is 0%, it is called feather. The higher the ratio, the better the quality of down.
Fill Weight literally refers to the total weight of the down in the item. This is measured in grams and is a helpful variable in determining the warmth of an item.
Product Weight is the weight of the entire finished product, regardless of fill-weight and fill-power.
