Yes it most definitely can be worn in all weather conditions.
It's very popular among the Basenoters especially because of the versatility you have already mentioned.
It suits not only every weather condotion but also every social situation like work, meeting, family, etc.
To me Rive Gauche is the typical barbershop smell that is to say gentlemen smell and i think i get this impression because of the way the vetiver and the lavender are blend together.
Anyway, you should definitely give this one a try.
welcome to BN by the way!
