Coming out 15 years after the modern classic Blue, Polo Ultra Blue is brand new take on the scent. Forgoing the more floral inlfuence of the original, Ultra Blue is crisp and citrusy, much cleaner and lighter. Vervain, lemon, citron and basil open at the top, with mineral heart notes of clary sage and juniper berry. The base of the cologne is salt, minerals, wood and AmbertonicTM, a patented and secretive cologne ingredient discovered in the past few years. Needless to say, Polo Ultra Blue is not only different from Polo Blue but also from most any other cologne. It certainly stands out even among the citrus-clean type.
