The Original Chillow proudly made in the USA feels immediately cool to the touch unlike hard overseas gel products. It feels soft and squishy like memory foam, no comparison to cold clay packs or gel that only becomes harder in the freezer. In fact, Chillow requires no refrigeration or electricity to cool you down into a comfortable state. It has a yummy spa like feeling that is relaxing, rejuvenating allow you to bounce back from an injury or a hard day at the office. It is your personal cooling spot whether on your pillow or your favorite chair or couch. We patented it using SoothSoft liquid technology using water for its soothing cooling non toxic heat wicking and releasing properties. There are no harmful foreign based chemicals or unknown gel ingredients. We simply use an evaporative cooling process - the Chillow draws heat from your head and then dissipates it back into the air using its large surface area. Don't be fooled by the small imitators - you need large surface area for maximum cooling capacity.
