The cop-invented TacVent is a lightweight, highly flexible, customizable rubbery plastic insert comprised of corrugated, vented grooves, designed to be placed between ballistic armor and the user's body, providing 1/2" of comfortable separation and allowing constant, passive and significant ventilation of heat, up to 14.5°, while minimizing moisture and odor, something that has never been done before.  A huge bonus is that the TacVent profoundly minimizes blunt force trauma! TacVent - the only solution in body armor ventilation. ™
