Apparatuses and systems are disclosed and can include a case for eyewear having an eyewear body carrying onboard electronic components that comprise a heat source that generates heat during electrically powered operation is disclosed. The case can hold the eyewear when the eyewear are in a stowed position. The case can further include one or more supports to support the eyewear in the stowed position within the holding space. One or more heat sinks are integrated with the one or more supports. Each of the one or more heat sinks are thermally conductive coupled with a corresponding heat sink of the eyewear. A first heat conduction pathway is thermally connected to the one or more heat sinks and can extend into the case body to conduct heat from the heat source into the case with the eyewear supported in the stowed position.
