For those who prefer a firmer pillow, the feathers in this blended-fill pillow feature natural "spines," which make for a more substantial feel. The core support of the feathers is wrapped in the fluffy luxury of domestic duck down for a superior-quality pillow with nothing but pure white fill. The preshrunk cambric cotton shell is closely woven to keep the fill inside. Down Alternative Bed Pillows and Premium Down Bed Pillows also available.
