Phoenix Armor announced production of the SWAMP COOLER utility T-shirt which will keep you 55% cooler. The patent pending, ribbed design T-shirt functions similarly to an evaporative cooling system. It acts as a protective barrier providing physical and sensorial comfort while regulating temperature, moisture, and friction when worn against the skin underneath body armor or other garments. This cooling and drying process is dissipated through three mechanisms attributed to the textile and the vertical welt ribbing: conduction, convection, and evaporation.
