Although lacking in projection and longevity, as far as the actual scent goes this is nothing short of exquisite. I do not know the OG, but as a stand alone fragrance Zion is really well blended, and in my opinion more suited to autumn than spring or summer, as the sweetness is not a zesty one. This sweet note lends itself to a more youthful vibe than a barber shop scent, for example. Strangely, the other day I got whiffs of Terre d’Hermès in the dry-down, whereas on first sniff there is no resemblance to TdH whatsoever. Must be the citrus. A complex, but extremely well-rounded composition which explains why this Alexandria offering is so successful. I just wish the performance were as good as the scent. I make up for it by spraying liberally.
