The ChiliGel cooling pad is engineered by using a gel to keep your head cool while you sleep. The pads are wrapped in a soft polyester cover to keep you safe, and offer a maximum level of comfort. The dimensions are 11.75” x 15.75” to fit all sizes of bed pillows.
In addition, the pillow pads last for three to five hours, to assure you are fast asleep by the time the pillow is back to normal temperatures. Of course, the product does last all night when used with the ChiliPad.
