Zahfran means "saffron", and this smells just like you've opened a jar of saffron threads, only smoother and heavier. I could see this mixed with something else, but unless you really like saffron, I can't conceive of wearing this on it's own.
Because it's made with only pure essential oils, it completely lacks the "cologney" quality that many fragrances have due to the synthethics.
And yet even without the chemicals, it lasts all day on me. Just don't expect a lot of sandalwood - it's pretty subdued.
The eucalyptus note is what tips the scale for some people. Personally, I love it, and it lasts all the way into the drydown on me. But as others have said, on certain people it can smell medicinal.
IMO, this is one of my favourite summer fragrances. It's refreshing, comforting, and manages to be substantial without being cloying, and smells completely different from the aquatic/citrus that most of the planet wears in summer.
