The Comfort™ Series is the popular choice among drivers who want the classic look, but who also want a major step up in performance characteristics that go beyond just color. With a unique metal alloy bonded to a special dyed layer, the Comfort Series gives you higher heat rejection and additional color options. Plus, since metal is impervious to fading, the sputtered metal/dye construction means the Comfort Series has even greater color stability than conventional dyed films.
