Bullard’s popular Isotherm Vest is now available in a high-visibility design that meets ANSI/ISEA 107-2010 Class 2 requirements. This new high-visibility Isotherm provides workers with a lightweight vest to stay cool when working in hot environments. This vest meets the requirements of the U.S. Department of Transportation Federal Highway Administration’s Manual of Uniform Traffic Control Devices when working in or near roadways.

The revolutionary technology of Isotherm offers workers hours of cooling relief in hot temperatures. Isotherm’s unique phase-change technology maintains a constant, pre-set temperature of 55º F. The cool packs within the vest keep workers cool. These packs can be recharged in 20 minutes in ice or cold water, providing hours of safe, controlled body temperature management. Wearing the Isotherm Vest helps reduce the chance of heat-related illnesses that often occur when working in hot environments.
