Phoenix Armor has announced the Swamp Cooler utility T-shirt, which the manufacturer says will keep the user 55 precent 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.

The cooling and drying process of the Swamp Cooler is dissipated through three mechanisms attributed to the textile and the vertical welt ribbing: conduction, convection and evaporation.
