Similar to Bonpland, Humboldt is also a citrus fragrance; however, the citrus note here is more subdued and Humboldt is slightly fruitier than Bonpland. An interesting variation of a citrus scent, Humboldt is also straightforward and free of unnecessary embellishments. He is more subtle than Bonpland and has a slight sweetness.
Personally, I prefer Bonpland, as I am not particularly fond of passion fruit scents, but compared to Mbucuruyá, Humboldt is truly wearable.
Sillage and longevity are again somewhat weaker here, but with passion fruits, this seems appropriate to me.
