This is Christopher Brosius's re-invention of the classic men's eau de cologne, back when that term represented a very specific blend of aromatics. They tend to be citrusy, herbal, and light.
CB's has a strong base lacking from the classics. It surprised me with its intensity and its deep heaviness. But i like that. Mmm-mmm-mmm.
It smells exactly like Aveda Gaiam did when they had it as a purefume. It's a wonderfully blended fragrance, but not for the shy.
Too herbal for my taste, it smells like some kind of aromatherapy oil or simply like crushing a leaf on a pottet plant between your fingers and then smelling your fingers. A green note verging on citrusy/minty/spicy/medicinal, I'm pretty sure the geranium is the culprit. As a cologne it lacks finesse, but if you really dig green scents and don't mind geranium it might work for you.
