Kozaye pillows are wrapped in a 3D-knitted hemp and bamboo viscose surface that keeps a layer of air between the user and the pillow’s ventilated memory-foam core. The pillow’s hemp exterior is roughly four to six times more absorbent than cotton, which keeps skin cool and dry. Hemp is naturally resilient against bacteria and mold, and hemp fibers become softer to the touch after washing. Kozaye pillows come in three sizes: thin, thick and contour. The pillows are backed by a three-year limited warranty, 100-night risk free trial and free returns.
