I'm still a fragrance noob, but I live where it is hot (really hot actually) far more than it's cold, so I was on a quest to find some awesome hot weather scents too. It doesn't get much love, but Lacoste Essential fits the bill nicely for me. I really enjoy the way it smells, and my wife does too. Also the top notes get reactivated with body heat. It leaves a fresh, subtle scent for most of the day.
