The FormulaOne "Comfort" Series Film is constructed with metal, and is a "hybrid" film that combines metal with a stabilized/dyed film and is completely non-reflective and looks smoky in appearance rather than being mirrored. The Comfort Film Series is guaranteed to never change color or fade to purple like standard dyed films tend to do over time. Reduces 44% heat, 99% UV rays and 60% glare.
