Actually there are two version of Eau de Patou: for Men (the cylinder one like Rive Gauche) and for Women (the pyramid-like one).
I only own the Men version. It opens with warm but still refresh citrus top note, then turn into a creamy/woody base. Sillage is fabalous in the first 30m, after that the scent stays close to skin. You may not smell it from a distance, but if you put your wrist close to your nose, it's still citrus/woody heaven.
On the other hand, according to reviews, Ho Hang belongs to diferrent league. I'd suggest you buy both since they are both staples or very good candidate for each of their category, and they are DISCONTINUED!!
