Abstract
Abstract Flexible icecaps for overlying the top of a user's head. The icecaps have plural chambers formed between inner and outer flexible material layers. A first embodiment includes an ice cap having a front chamber two side chambers and a rear chamber which are each separated from one another wherein at least one chamber can be filled with a coolant liquid such as ice, so that icecap can be partially used for localized headaches. A second embodiment includes two front chambers, on the right and left side, and two rear chambers, on the right and rear side. Chin straps can be used to hold the cap in place. Elastic bands can be used to separate each of the chambers and aid in elastically holding the cap in place on the user's head. Waterproof portals can be used to access each of the chambers on the top of the icecap. Portals can be either screw on caps or rubberized plugs. A third embodiment includes a single flexible layer shaped as a helmet to fit over the head of a user. The outer surface of the layer can have hook and loop type fasteners wherein individual prefilled pouches of coolant liquid having hook and loop fasteners on an exterior surface can be mounted to the exterior of the flexible layer. Alternatively, the exterior surface can have pockets with side openings sized to snugly receive prefilled pouches of coolant liquid.
