What Is Down Fill Power? | Rab Lab
What is down fill power?
Fill power is all about quality, not quantity. Higher fill power down lofts more and traps more air relative to its weight, making it a great choice for activities and environments where both weight and warmth are critical.
We use a range of fill powers in our down jackets, strategically chosen for each jacket’s intended use. Learn about fill power and how it affects the warmth-to-weight ratio of your down jacket.
