I'm in California east bay. I got my wife a new X3 and she's looking for a quality sun protection shield for both driver and passenger windows. The rear windows are tinted. While I can find some of these where you can roll them up and down, she's not happy with those. She wants something really really nice. She's got sensitive skin so she's looking for a good quality to protect her skin from sun-damaging sunrays. We will only use them in the summer, we will hardly use them in the winter. Please any suggestions?
