The cop-invented and American-made TacVent is the first and only body armor ventilation device that allows the unobstructed flow and release of heat through true separation, using actual space, not material. Testing has shown TacVent to lower body surface temperatures by at least 14.5°, its distinctly unique and patented design consisting of a corrugated and perforated panel of extremely soft and highly flexible, engineering-grade, hypoallergenic thermoplastic elastomer. A huge plus is that its design and material allow it to act as a cushion, profoundly minimizing blunt force trauma. (less)
