The 3-Temp-Zone Comforter makes temperature disagreements a thing of the past. Thoughtfully designed with NASA-inspired technology, this comforter regulates body temperature throughout the night. It strategically uses fill levels to keep sleepers comfortable, with less fill in warmer areas and more where it's needed for colder spots. Silver-infused fabric inhibits up to 99.7% of bacterial growth, promoting a cleaner and fresher sleep experience.
