Where does the HS get its cooling power?
The HS relies on two patented technologies that deliver the cooling power of two phase shifts. The patented synthetic ice core delivers incredible cooling and the patented design keeps you dry as well. Used continuously or sporadically (breaks) the HS keeps you cool. The HS also has been used with great results in a Rehab environment to cool people who are already overheated or are suffering from heat stroke.
