Wow i am impressed. I am not really a fan of the scent itself, but the longevity is amazing. One spray just passed the 14 hours mark on my skin. Decent projection was still there after 6 hours, then it turns slowly into a skin scent.
Unlike La nuit de L'homme which baaaarely lasts 6 hours in total, and the last three are just a powdery mess, this one keeps its integrity all this time and you definitely know that you sprayed Rocky Mountain on yourself, and not a cheap baby powder.
Overall i find the smell to be a bit cloying in the beginning, even for colder weather, and it could definitely considered unisex. The violet in it gives a very strong feminine vibe.
