United Tactical Gear's new CoolShield is a baselayer designed to keep law enforcement officers cooler and safer under their ballistic armor. NTOA tested and recommended, CoolShield improves on the comfort of a moisture-wicking T-shirt with elongated, vertical ribs, three in front and two in back. It is made to be worn under armor, in place of the usual T-shirt or turtleneck. CoolShield’s flexible, lightweight rib material creates spaces between the vest and skin to promote ventilation, moisture transfer, and temperature regulation.
