Elegant, understated, masculine
This is probably my favorite vetiver fragrance, although Sycomore by Chanel comes close. It has a really addictive grapefruit/vetiver interplay in the opening that's very fresh, but not in a gauche "sporty" way. There is also a fair bit of orris root that I believe contributes quite a bit of the character to the vetiver note. Fair bit of Iso E Super in the drydown, along with probably about as much oakmoss as is legally allowed to play up the woody aspect of vetiver.
A word of advice, though: I would describe this as a vetiver for people who hate vetiver. If this is your first vetiver-focused fragrance, do not think this is an archetypal example. It isn't. It's lovely, but there's nothing else like it. There are other fresh-smelling vetivers out there (Creed Original Vetiver, Mugler Cologne), but they smell considerably more soapy to me. There are also much dirtier vetivers, like Guerlain Vetiver, Chanel Sycomore, and the somewhat infamous Encre Noire.
Ultimately, one of the best in the Tom Ford stable, and easily one of the most versatile men's fragrances available. Elegant, understated, but distinctly masculine.
