  • Patent number: 10993494
    Abstract: A head cover that can be worn by health care professionals is provided. The head cover includes a surgical cap portion and a bouffant cap portion. The surgical cap portion includes a top surface and a side panel secured to the top surface via a seam. Further, the bouffant cap portion is secured to a rear portion of the side panel, where the bouffant cap portion is maintained against the rear portion of the side panel in an undeployed state and is deployable from the rear portion of the side panel to contain a wearer's hair. As such, the head cover enables a wearer to secure his or her hair inside the bouffant cap as needed, yet bouffant cap portion does not cover the wearer's entire head, which minimizes the amount of heat that is trapped within the head cover and increases the level of comfort for the wearer.
