37.5 Technology Cooling Bed Pillow

37.5® Technology helps keep your body at the ideal core temperature of 37.5° Celsius and helps keep the microclimate next to your skin at the ideal relative humidity of 37.5%. When you are hot, patented 37.5® Technology active minerals embedded in the materials remove sweat in the vapor stage before liquid sweat forms, helping to cool you down. When you are cold, those same active particles use your body’s own energy to help keep you warm. Covered with an 80% cotton/20% 37.5® twill fabric and filled with a blended 80/20 polyester/37.5® down alternative fiber, these pillow are machine washable and hypoallergenic. Available in Standard and King Size.
