I put up a mesh top one year and the crew said if I didn't take it down they were all quitting. It was way to hot under it to work. I put up the solid silver one and they went back to work. Still have the mesh rolled up in the trailer...SCTA still uses Mesh ones for inspection but the seem to be different. I believe there are more than one grade and they may have the ones which block out more sun.
If you ever get the get a white "Easy-up" cheap you will know why it was cheap..That only worked for a year and I bought a new blue cover.. Cook actually said black was the best...Never had one though............Good Luck
