Rab Down Fill Power Explained

Many jackets are sold off the back of their fill power rating, but the measurement is easily misunderstood. In this video, Rab Product Marketing Manager, Gemma, explains exactly what fill power is and why we use a wide range of down grades in the manufacture of our products. Fill power refers to the quality of down. Fill power does not refer to the amount of down used and it cannot be relied upon to give an idea of a product’s warmth, unless, that is, you are also considering the product’s 'fill weight' too. We grade down according to the size of the clusters, that is the amount of air that the down is able to trap relative to its weight. To do this we take 1 gram of fully lofted down and record its volume, the result represents the down’s “fill power”. All of our Duck down is 650FP and our Goose down ranges between 750 and 1000FP. The range of down that we use allows us to fine-tune our garments to meet the differing demands of our customers, both in terms of budget and intended use.
