What is Fill Power in a Down Comforter?
The quality of down is determined by Fill Power. The higher the Fill Power, the better the quality of down comforter. The Fill Power number represents the number of cubic inches one ounce of down occupies in a comforter. One ounce of a 600 Fill Power down comforter will occupy 600 cubic inches. A 300 Fill Power down comforter would require twice as much weight to replicate the loft and warmth of a 600 Fill Power down comforter.
The higher number is not always right for everyone in every climate. That's why we have a huge selection of quality down comforters available online and in our store. If you have any questions, please call or email us anytime!
