CK One Cologne is a clean and refreshing fragrance that was designed for a dynamic, free-spirited man who is able to see the good side of everything. Introduced in 1994 by Calvin Klein, it is a light blend of bergamot, lemon and mandarin at the top, with middle notes of jasmine, lily-of-the-valley, rose and orris, all balanced out by base notes of cedarwood, sandal, amber and oakmoss. Green and simple, CK One cologne is recommended for daytime and casual wear.
