There are a lot of things you can't control while traveling. Don't let your temperature be one of them. The GEL DOUGH + Z Gel? pillow offers a unique dual-gel approach to combat heat. Ultra-cooling Z Gel? lies on top of the pillow for a cool sleeping surface that captures and distributes body heat. The memory foam is also infused with cooling Z Gel? for a combination that offers an optimal thermal experience.
