I recently ordered one of these cases from Amazon:

This case was purchased because the ad says it will hold the Goggles 3 and controller. It does - barely. The controller fits fine but the goggles are very tight and the case bulges when zipped closed. The title also says this is a hard shell case which is real stretch. There is something semi-hard under the cover, but it is thin enough to be flexible, so don't expect much, if any protection against an impact. Finally, there is no extra storage in the case for extra items such as a HDMI mini cable.
Still, it does what it says and provides more protection than carrying your goggles in a shopping bag. Barely. Cost was $25.98, which is a bit over priced, IMHO.
