RS7 rear window privacy shade

[Artorious]

Has anyone found a good privacy shade for the rear passenger windows on A7/S7/RS7? I have crystalline on their but would like more privacy if possible. Don't want to add another layer of tint as windows already seem slower to roll down with crystalline on there. I saw windesa product that seems like a good solution but they only have rear hatch and small quarters. the problem with the rear windows is there is absolutely no frame on front/top/back sides. Hoping someone has found something.

If your looking for something to reduce the sun/heat even further, and can accept not opening the windows while fitted, Google "Audi Window Sox". This may be what your looking for if your carrying children in the back.

If it's simply not dark enough for you, then striping off and putting on a darker tint is really the only solution when you have frameless windows.
