The StaCool Vest™ Core Body Cooling System, now available in luminescent safety colors, is helping workers beat the summer heat, allowing work zone employees to stay safe, cool, and productive despite elevated temperatures. Fully adjustable models are available in safety yellow, orange, and green and provide all-day comfort with unrestricted mobility. Under-vests are also available, to be worn under clothing, so there is a StaCool Vest™ to suit any style, preference, and application. ThermoPaks around the vest provide hours of cooling; a spare set of ThermoPaks are included with each StaCool Vest™ to extend cooling time and comfort when the initial set thaws.
