- Roll-Up or Retractable Shades: These are convenient for daily use since they’re easy to put up and take down, but may not cover the entire windshield perfectly.
- Reflective Shades: I preferred reflective materials because they do a great job bouncing sunlight away and keeping the car cooler.

- UV Protection: The shade needed to block a high percentage of UV rays to protect my interior.
