Eternity Cologne by Calvin Klein 1 oz Eau De Toilette Spray for Men. Calvin klein’s iconic eternity line began with the original launch of the women’s version of the scent in 1988, only to be followed the next year by this men’s version of the scent. Classified as a refreshing spicy, lavender, and amber fragrance, eternity is a real classic of men’s fragrances. This masculine scent possesses a blend of greens, crisp jasmine, sage, basil, and rosewood. While the scent isn’t specifically made for date night, eternity is so associated with attractive, successful men that it is bound to work well in that setting as well as pretty much any other. Try it for yourself, and see what everyone has been raving about!
