Iso Cool pillows and mattress toppers feature Outlast Adaptive Comfort material that adjusts to the body's changing temperature. The microscopic Phase Change Material (PCM) beads sense whether the body's mean temperature is too warm or too cool. If the body's temperature is too warm, the product absorbs heat and feels cool in order to regulate body temperature.
