600 Fill Power Down Pillows

Because 600 fill power down clusters are smaller than a US dime you can fit more small down clusters, or dimes, into the pillow shell. That down pillow will now be heavier because it will have a higher FILL WEIGHT. Fill weight, the number of ounces of down used to fill a pillow shell for a given density; soft, medium, firm or extra-firm, are higher when the down clusters are smaller.
