Polo Ultra Blue by Ralph Lauren Cologne. Polo Ultra Blue is a crisp combination of citrus and aquatic accords. Introduced in 2018, this fragrance is as invigorating as a cool, salty ocean mist. It is perfect for a man who works hard and plays hard, too. The cologne opens with a blast of energizing citrus scents with notes of lemon verbena, basil, citron and lemon. Next up in the fragrance are musk and ambertonic notes, creating a heart that is deep with musky, amber and powdery undertones. The cologne closes with dry notes of woods, musk and salt for that sea breeze feel.
