This pillow is made with care in Canada with Canadian fill. The outer shell is soft 400 thread count cotton. This is a 3-Chamber pillow, containing down and feather farmed by the Hutterites in the Canadian Prairies. The majority of the fill (about 90% of the total fill weight) is feather, which is in the center chamber. The feather core provides great, resilient support due to the feather quills. The outer chambers are filled with 700 loft down, which creates a soft buffer against the feather. Down Perfect pillows combine the support of feather with the softness of down for the best of both worlds.
