ABSTRACT:
A non-fogging athletic goggle or mask assembly, comprising an athletic goggle or mask in combination with a desiccant assembly, is disclosed. According to one embodiment, an athletic mask or goggle is provided with at least one desiccant chamber formed in a portion of the mask or goggle so as not to obstruct vision. The desiccant chamber includes a gate that can be deployed or retracted to close off or expose the interior of desiccant chamber. The desiccant chamber is provided with a tablet or pre-packaged desiccant, which is retained within the desiccant chamber during use of the goggle or mask and can be replaced upon saturation. When the mask is worn, water vapor in the air trapped by the goggle or mask is absorbed by the desiccant, thereby preventing fogging of the goggle or mask. The desiccant capsule or the desiccant chamber may be further provided with a water vapor permeable membrane that allows water vapor to pass but excludes liquid water. The desiccant material may be combined with an indicator substance that changes color as the desiccant becomes saturated with water.
