Ck One Cologne by Calvin Klein, Ck One has remained at the top of most must-have perfume lists since its introduction in 1994. A versatile fragrance for men and women, this aromatic chypre combines green and fruit notes to culminate in a fresh, clean scent. The top notes are pineapple, bergamot, and papaya. These blend beautifully into a warm heart with middle notes of jasmine, rose, and violet. The dry down is sensual and deep with base notes of amber and musk.
