1 PC Car Sunroof Sun Shade, 3.28Ft x 2.13Ft Breathable Foldable Vehicle Sunroof Mesh, Keep Cool, No Tool Installation, Universal Durable Automotive Sunroof UV Sun Protection (Black)

I needed extra airflow and wanted to keep pests out so this worked perfectly.

I slept in the car during an afternoon at scout all-day activity. I opened the sunroof and covered the top with this mesh shade. It worked as described. I did take it off during the driving. I noticed the surface gaps in the fabric where the magnets have space for the cloth folding. I did put the shade stretched flat without any creases or gaps. With high speed driving I thought that it would start folding and pulling up. If the sunroof is closed, it might be fine. If open then the airflow and drive speed might cause a pull. I might try it on an sunday morning when the streets are empty.As for the idea, it is good. The magnet strips are not super strong but do stick well and flat. The mesh cloth quality is good. The stitching is good. The size of the sunshade cloth fit well for both the van and the sedan. When folded it the size of a small umbrella. I am sure this rectangle magnetic sunshade might work for other applications too.
