I think its more of a woodsy, musky, fragrance. Like a lot of CK products, you only need a little for a lot of wear. However if you look it up on the Internet it will describe to you exactly what CK put in this. Also if you're not sure still, go to your local Macys or Lord & Taylor, try it on your body as what smells nice on paper, or on someone else, may not jive with your body chemistry.
I agree with chellynthomson.... I recently acquired a sample vial of this from listia. And though I like the smell in first 10 mins, it doesn't smell so good after that. And totally disappears in 30 mins. It practically didn't last at all on me. So if you can, you should try this out at store to make sure.
