I.C.E. Body Armor Vent Retrofit Kits are a paradigm-shifting invention because, for the first time in the history of body armor, there is now continuous air flow between the plate carrier and the wet base layer, creating evaporative cooling. The RFK consists of two flexible, extremely lightweight, scientifically sculpted, fabric/foam panels that can easily be worn under all existing body armor. The air flow chimneys and horizontally punched holes throughout the panels allow air to flow south to north and circumferentially. It dramatically maintains continuous natural evaporative cooling.
