Down is the soft fluff that comes off the duck.
As you can see from above that Down is three dimensional and can trap air very easily, making for good insulation and keeping you warm. Also when the body begins to overheat the natural fiber of down has the ability to breathe and absorb body vapor preventing you from overheating and sweating while you sleep.
