me too. anything you like it doesnt seem to fight with anything . i have polo sport today works fine.Same as above. I use whatever I want with it, most often Clubman or AV Ice Sport.
I also think any scent should work after using the Fat, but find myself reaching for Proraso splash or Aqua Velva most often.
It's Rosemary.
Just about any of them as MWF has such a neutral/fresh scent. It won't clash with any after shave.
