First of all, I live in a tropical weather region, in a beach city. I've been using Polo Blue for almost three years, everytime I can.
Well, I really don't understand why people say it has poor longetivity, because it lasts 6 hours on me at least. Maybe my body chemistry?
Sillage is not good, in order to smell it you have to be close to the wearer - but sometimes that's what you really want to happen when you wear a fragrance, right?
The fragrance by itself is great! It is deep, but not overwhelming. Women really love it and they will remember the scent when they smell it again.
Big thumbs up. I really like it and everyone around me too.
