ABSTRACT:
A ball type umbrella covering the head and extending below the top of the shoulder line being held in place by a draw string arrangement. The umbrella device is double layered with means of inflation thereof providing optional inflating means at two points within and without the device. The two layers are welded at a multiplicity of points whereby the ball or globular appearance of the umbrella is substantially maintained after inflation and during use due to uniformity of air pressure throughout the interlayer space.
