260 thread count cotton down proof shell 50% hotel goose down pillows

This pillow filled with 50/50 goose down and feather.  Down is the fiber cluster on the abdomen of geese, which is shaped like a reed flower. Down is a type of animal protein fiber that has higher warm-keeping ability than plant-based cellulose. It contracts and expands with temperature changes and has a temperature regulating function. The down fiber is three-dimensional which contains a large amount of air inside to block cold air. The goose down pillow is dry and can quickly collect and expel sweat from the human body during sleep, and automatically adjust the temperature to achieve warmth in winter and coolness in summer.  Shell cover with an downproof treatment fabric upto 260 thread count percale weave, effectively prevent the down from running out.
