Abstract
A valve for an inflatable device includes a pocket configured to be located in a cavity of the inflatable device. The pocket includes an entrance opening to receive air from an air output. The pocket further includes a first layer of material having at least a first aperture, wherein the first aperture is positioned entirely within the first layer of material, a second layer of material having at least a second aperture in fluid communication with the first aperture, wherein the second aperture is positioned entirely within the second layer of material. The first aperture and the second aperture are in fluid communication with the entrance opening and the cavity such that airflow passes through the valve by flowing from the entrance opening into the pocket, and out of the pocket and into the cavity through at least one of the first aperture or the second aperture.
