No more uncomfortable, hot nights with my Essential Cooling Mattress & Pillow Bundle! Made of a silky soft fabric, this set uses a cooling fiber technology that disperses your body heat five times faster than regular polyester protectors. Both pieces of the set also also contain a wick away function that manages moisture and transports perspiration away from the body- so you'll stay cooler even if you're a super active sleeper! And besides providing a cooler sleep surface to keep you drier all night, they also protect your mattress and pillow from liquid stains, dust mites and allergens. This is exactly what you need to maintain a cleaner and more pleasant sleep environment!
