The term aquatic is pretty self explanatory. It refers to scents that smell fresh and "watery". It's a little hard to describe but when I think of an aquatic fragrance, I think of a beach and what the ocean smells like. Have you ever came home from the beach and found that your clothes still had that beach smell? Well that's what aquatic colognes smell like to me. They've been pretty popular recently and many of them smell too much alike so different companies try to add their own twist to the scent by throwing in citrus notes. If you want some good aquatic scents then I would recommend you try out some of the popular ones such as acqua di gio, polo blue, and aqua quorum just to name a few. They're really good for the daytime when you don't want anything too strong.
