This non-fluctuating sound profile allows the noise filtering and processing found in many common law enforcement and first responder microphones to more easily identify and reduce the background tone.\u003c\/p\u003e\n\u003cp\u003eThis helps officers communicate over portable radios, shoulder microphones, and other common public safety communication equipment without the fan repeatedly surging into the transmission.\u003c\/p\u003e\n\u003cp\u003eMicrophone performance may vary by radio system, microphone placement, noise reduction technology, fan position, and surrounding conditions.

However, sweat only provides meaningful cooling when it is able to \u003cstrong\u003eevaporate from the skin\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eUnder a ballistic vest, moisture can become trapped between the wearer, uniform, and armor. The enclosed space quickly becomes warm and humid, which limits evaporation. When sweat remains trapped against the body instead of evaporating, it provides less cooling and can leave the wearer feeling soaked, overheated, and uncomfortable.\u003c\/p\u003e\n\u003cp\u003eVestFlow™ helps address this problem by continuously moving air through the space beneath the vest.\u003c\/p\u003e\n\u003cp\u003eThis airflow helps:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDisplace warm, humid air trapped beneath the armor\u003c\/li\u003e\n\u003cli\u003eIntroduce moving air across damp clothing and skin\u003c\/li\u003e\n\u003cli\u003eIncrease the rate at which sweat can evaporate\u003c\/li\u003e\n\u003cli\u003eReduce moisture accumulation beneath the vest\u003c\/li\u003e\n\u003cli\u003ePrevent stagnant pockets of hot air from remaining against the torso\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eEven when outdoor temperatures are high, moving air can still improve comfort by helping moisture evaporate and by replacing the humid air trapped beneath the vest. The effectiveness of evaporative cooling will vary based on temperature, humidity, clothing, activity level, and individual conditions, but airflow can remain beneficial even when the surrounding air is not cold.\u003c\/p\u003e\n\u003cp\u003eVestFlow™ does not simply blow cold air. It helps the body make better use of its natural evaporative cooling process.\u003c\/p\u003e\n\u003ch2\u003eMore Than Comfort\u003c\/h2\u003e\n\u003cp\u003eWorking in body armor places an additional heat burden on the body. Hot weather, direct sunlight, physical exertion, limited airflow, and long periods in uniform can increase the risk of heat-related illness.\u003c\/p\u003e\n\u003cp\u003eVestFlow™ helps improve air circulation beneath the vest, supporting a more manageable working environment during demanding conditions. It should be used as one part of a complete heat-safety plan that includes proper hydration, rest periods, shade, appropriate supervision, and recognition of heat-illness symptoms.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVestFlow™ is not medical equipment and does not prevent heat exhaustion or heat stroke.
