We use the latest PA material, the brown and black translucent panel protects against UV rays and can isolate hot and cold air more efficiently than traditional baffles by more than 50%, which can cope with extreme weather more effectively. Improved magnetic closure technology and high-density dust strips provide a stronger seal, which not only resets the baffle better, but also effectively prevents dust, insects and wind from entering.
