Bullard® ISO2 Cooling Vest, M to L, Blue, Proban Treated Cotton, Isotherm® Cooling, Hook and Loop Closure

Isotherm® is a revolutionary technology that offers more cooling, lasts longer and is more comfortable than any other cooling product on the market. Tests have proven that the Isotherm® cool vest stays within the human comfort zone much longer than any other product. Unlike ice or gel packs that quickly lose their cooling, Isotherm's unique phase-change technology maintains a constant, pre-set temperature that will provide hours of effective cooling to the user. The cool packs within the vests can be recharged thousands of times, providing hours of safe, controlled body temperature management.
