Zephyr

The Tigeraire Zephyr is a Clip-On Cooling Fan designed to cool you down with a gentle airflow. The lightweight device clips onto the brim of a ballcap, the collar of a shirt or anywhere else cool air is needed. Air movement can keep the skin safe from sweat and bugs. 

The Zephyr is powered by a built-in, rechargeable LiPo battery that can last over 10  hours on a single charge.
