CK IN2U For Men

CK IN2U for Men, 2007, was Calvin Klein's scent for the first generation to conduct its private life in public. It still reads that way: brash, immediate, not much interested in subtlety.

Bright mandarin and a green cardamom note open it, with cocoa and birch leaf through the middle giving it an unusual dry bitterness, and white musk and vetiver underneath. The cocoa is the part people remember — it keeps the citrus from going generic.

Eau de toilette.
