Abstract
Abstract This air cooling device includes a waist belt worn under the clothing of the wearer and having an apertured, waist-encircling air tube attached thereto. The air tube is connected to an air supply by means of an extension air line having an air pressure reducing regulator valve at one end. The device also includes an apertured neck-encircling air tube attached to the waist-encircling air tube. The ends of the waist tube are separable to facilitate removal from the wearer with the waist belt.
