Abstract
A cap construction including an exterior layer coextensive with an interior layer defining an cap-shaped structure including an elastomeric band to enhance securement of the structure overlying a swimmer's head portion. Sandwiched between the layers are a matrix of enclosed pneumatic chambers to afford a protective covering to the swimmer in use. A modification of the instant invention includes a plurality of coaxially aligned pneumatic chambers directed exteriorly through the opposed layers defining an elongate chamber defined by an ellipse of revolution. A further modification of the instant invention includes a series of spherical chambers captured between the layers including interconnecting conduits, wherein the conduits are secured at intersections with each pneumatic sphere defining a medial axis about each intersection with apertures directed through the conduits interiorly of the pneumatic chambers, or spheres to permit equalization of pressure throughout the matrix of spheres.
