The Smart Temperature collection is the ideal solution for those searching for a complete temperature management sleep system. The intelligent thermoregulation two-step system works by firstly offering a cooling sensation before the first sign of moisture. It can also sense an increase in body temperature which then activates a unique cooling effect allowing moisture to evaporate, mimicking the body’s natural cooling mechanism. When the body has reached its ideal temperature, the reduced body heat will guide the cooling effect to ease back so that you won’t feel a chill. This technology works through all types of linens.
