800 vs 850 vs 900 Fill Power Down Comforter

The 3D baffle-box construction. The same cloth is used on all three comforters.

Loft, not weight.

Fill power measures loft. One ounce of 900 fill power down takes up more space than one ounce of 800 fill power down. A higher number is loftier down. It is not a heavier comforter.

Haven, Serenity, and Elysian use the same fill weight. The 3D baffle-box construction in the photograph is the same on all three, so it is shown once. Explore our three fill power levels: 800, 850 and 900.

Why 800–900 fill power matters

Haven, Serenity, and Elysian use the same fill weight. A higher fill power is loftier down, not a heavier comforter. The drawing is a comparison, not a measured slice of the bedding.
