COOL Zone’s longest duration Cool Vest is available from OTB Products .
Safety and extended suit-up time are the hallmarks of the vest, which is especially effective in Level A, Level B, JS-List, MOPP2/4 with SCBA, LBE and other ensembles.
The vest provides up to four hours of safe body temperature management in anatomically designed "optimum" temperature cooling.
Cool Zone's controlled-temperature phase change technology outperforms all copycats in fit, form and function. The company’s heat transfer formulas and thermal wave sealing and designs are not featured in other clothing.
Cool Zone's technology has been extensively instrumented, with field and human factors tested on the product (tested by Alamo Research Lab), which prove the technology safely increases work tolerance time by 22% with no significant change in core body temperature, blood pressure or heart rates if they wear Cool Zone’s personal protective apparel.
Cool Zone maintains the "optimum cooling temperature" required for maximum heat abstraction providing hours of effective relief from the health risks associated with heat related illnesses.
