What is the difference in Fill Power, Fill Weight, and Product Weight?

Fill Power, 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.

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.
