Calvin Klein Dark Obsession Men's Eau de Toilette Spray 4.0 Calvin Klein presents Dark Obsession, a new masculine addition to the collection, in early 2013. Dark, opulent and addictive, the new Dark Obsession fragrance is described as powerfully masculine and intensely sensual. The composition is a modern aromatic-oriental. It begins with bitter notes of Brazilian green mandarin, guarana and absinthe. Woody and aromatic tones of French clary sage, fir resin and white vetiver form the heart. The base is extremely warm due to Madagascar vanilla bean, suede and labdanum.
