With over 1000 Sun Shades sold, now available on Amazon. The Mevo Shade Pro is designed to keep the sun's rays off your Mevo so it keeps filming without overheating. Anyone who has tried to record with one in the summer outside knows they heat up fast and then shut down. This cover is printed in high temp resistant PETG and white to reflect as much of the sun's energy as possible. There are a small air gap above the camera and side air vents to help dissipate any heat generated. This shade is completely passive in operation. It relies on the thermal convection to allow the heat to rise and exit the side vents.
