1. Specially Designed for BMW: Our front windshield sun shade is designed for BMW vehicles, featuring reinforced steel rings for a secure fit that does not require suction cups. It does not sag or collapse, ensuring a proper fit for BMW i3 (2014–2022). 2. Double Layer Sunshade: The windshield sun shield is constructed with a double-layer heat shielding fabric. The outer layer is 240T reflective polyester, and the inner layer is high-quality fabric, providing enhanced insulation and protection from the sun. 3. Easy to Install: The sun shade installs quickly without tools. Use the vehicle’s sun visors to hold it in place by pressing them down. Installation takes only seconds and is simple to use (refer to the installation video on the product page). 4. Easy Storage: The front windshield sunshade features a steel ring design that allows it to be twisted and folded compactly. To store, fold and twist it into an '8' shape (refer to the storage video on the product page), place it in the included storage bag, and store it conveniently anywhere in the vehicle.
