Makes of Cool Zone Body Armor Cooling Inserts

The 50 Degree Company in Melbourne, Florida, produces Cool Zone, a controlled-temperature phase change technology that outperforms all cooling technologies in fit, form and function. Cool Zone proved its mettle during the 1996 ValuJet investigation for the Underwater Recovery Team. Extensive field and lab testing has shown that Cool Zone maintains the "optimum cooling temperature" required for maximum heat abstraction, providing hours of effective relief from health risks associated with heat-related illnesses. Cool Zone safely increases work tolerance time by 22% with no significant change in core body temperature, blood pressure or heart rates.
