Our Cooling Fiber Pillow Protector is constructed from high-quality soft knitted cooling fabric. The soft jacquard knitted construction provides a soft and cool feeling on the surface layer which also permits vapor transmission so that the air flows freely. With its capacity to naturally wick moisture away from the skin, resist odor, and provide a cooler sleeping environment, this eco-friendly cooling material can improve breathability and ventilation. This generates an atmosphere without moisture improving your quality of sleep.
