The most luxurious synthetic down in the world is Suprelle™ micro fiber. It cleverly mimics natural down in weight and feel, soft and light. When compressed, just like down, it rebounds to fill the orginal shape. The 400tc pillow casing is the same quality ticking as for down products, with double needle stitching and piping. Your pillows can be washed/dried , on delicate in over-size machines. We recommend using a pillow protector to reduce the necessity of washing. Made in Canada.
