Calvin Klein CK One Unisex Eau de Toilette is the cult classic for a diverse world, capturing the universal human spirit that exists inside each and every one of us. Unapologetically bold, this is a men's eau de toilette and women's eau de toilette in one, a youthful, fresh proclamation of the energies that flow within us all. A clean, sharp celebration of our differences and similarities, in a unisex perfume evocative of limitless opportunity, for those unafraid to break with convention. Gender-fluid and uncategorisable, this green citrus perfume from master perfumer Alberto Morillas is an uplifting accord of green tea, papaya, and bergamot to refresh, grounded in the heart with perfectly balanced notes of nutmeg, violet, cardamom, and rose and deepened at the base with glorious amber and musk for a muted, blurred quality.
