1. Specially Design for BMW: Our front windshield sun shade is specially designed for BMW, featuring reinforced steel rings for a precise and secure fit that doesn't require suction cups. Unlike other car heat shields, it won't sag or collapse, ensuring it is a perfect fit for BMW i3 (2014 2022). 2. Double Layer Sunshade: The windshield sun shield for BMW is made of a double layer of heat shield fabric to keep out the sun. The first layer is premium 240T reflective polyester, the second layer is high quality fabric. It provides double insulation and protection. 3. Easy to Install: Our sun shade is easy to install without tools. You can use the two car sun visors to hold it in place by pressing down on them. Installation takes just a few seconds and is truly easy to use (Please refer to our installationstorage video). 4. Easy Storage: The car front windshield sunshade is designed with a 'steel ring' that can be ly twisted and folded. When you want to store it, just fold it up, twist it along the steel ring to form an '8' shape (Please refer to our storage video on product link), put it into the storage bag that comes with the product, and it can be stored anywhere in the car to save space.
