Abstract
A ventilated garment includes a head cover and a ventilation system associated with the head cover. The ventilation system can include a helmet supported by the wearer of the garment and a number of piezo fan assemblies mounted on the helmet. The piezo fan assemblies includes a number of piezo blades that generate airflow from piezo-induced oscillation of the blades. In certain embodiments, the piezo fan assemblies can include multiple outlet ducts to provide directed airflow in multiple directions.
