airfiber disperses body heat and the heat of a blanket thanks to the unique ability to allow airflow through the material. Airweave gets rid of the usual problem of uncomfortable hotspots that most mattresses generate. Control the temperature of your overall sleep environment with the blankets you choose. During the winter, add a warmer blanket to hold in warmer, dispersed air. For warmer months, use a lightweight blanket and you'll enjoy a cooler airflow.
