Infused with graphite and phase change material for constant temperature regulation that maintains optimum sleep temperature. Graphite’s excellent thermal conductivity creates pathway for moving heat away from the head and neck. Surface coated with Omniphase phase change material, an advance cooling technology that continuously absorbs and dissipates heat. Tencel mesh removable cover, superior moisture transfer properties, aids in cooler sleeping temperature. Ventilated for increased airflow and breathability. Soft, supportive memory foam.
