Very good choice for car windshield protection. Very well-made construction with the perimeter cord and fabric of very good thickness and not fake with a soft layer in contact with the glass. I got the large size to avoid leaving gaps for the rays and thus I can also put the windshield wipers inside, which should be protected from the sun's rays, otherwise they burn and their lifespan is reduced, and they don't do their job properly.

Soft back side. It does its job. Definitely better protection than those that are single cloth.
