What is Down, Fill Power, Fill Weight?

When you think about down, you can as well picture a bird’s plumage in your mind. A bird’s plumage is that fluffy, fleece-like, soft undercoat you will see beneath the thick feathers at the below part of the bird’s belly. Many of the down types available today are gotten chiefly from geese and ducks, and irrespective of which of them the plumage comes from, the more grown the bird is, the larger one can expect its plumage to be. This leads to a higher loft and a greater down fill power rating.

The loft of a down item is indicative of the item’s fill power. Fill power further describes the durability and quality of the down. You achieve the highest level of loft when there is maximum expansion on the down clusters. Thus, the fill power rating is determined by from the down through some specific measurements and instruments. The fill power rating of a jacket can vary from 300 – 900 and beyond. Many products developed from down are characterized by down ratings of 400-500 which is often considered of low quality. But at not lesser than 550 fill power rating, quality of the jacket (or even any product) is guaranteed.

As opposed to fill power which is volume based, fill weight is of course a measure of weight. Essentially, fill power is indicative of the quality of a jacket while fill weight tells about quantity. A jacket of 12 ounces of down weight implies it was made with 12 ounces of down.

Down to Feather Ratio

The down to feather ratio is the quantity of down the jacket has on the inside, to the quantity of feathers. The larger the number of down present over the feather in the jacket, the warmer the jacket. For high quality down jackets, they should come with down to feather ratio of at least 80 to 20. 90 to 10 is fairly okay, and a down to feather ratio of 70 to 30 is best for temperatures that usually all above 4-5 0C

We have rounded up the best down fill jackets you will find at different fill power values and temperature ranges.
