With hypoallergenic DuPont® polyester fiber, water should be able to float on top of this pillow, giving your head nice cushioning, as well as preventing body heat and sweat from seeping through it, making sleep cooler and more comfortable.

Body heat causes sweat that works its way through the neck, head and the shoulders which is most likely to cause restless sleep. This pillow prevents all of that, and it continuously responds to your position.

The thing that does the trick? It’s water, which is contained inside the pillow.
