Blended with soft silky Tencel fibers and recycled polyester (30% Tencel and 70% recycled poly) to create soft clusters that cradle your head while you sleep. The clusters are made in the same way as our ever-popular Woolly Bolas, but have a softer silkier feel. As with all of our fiber pillows, the fill is totally adjustable to your liking and the Tencel/Poly knit cover features a zipper for easy fill removal, making it perfect for all types of sleepers! Tencel is a great fiber for sleep products because it is moisture wicking, breathable, and silky. Tencel is a manufactured fiber from Austria using 20% less water than cotton and comes from sustainable Eucalyptus trees. Made in the USA.
