As far as I am aware, (and please correct me if I'm wrong), the following Floïd products are those currently available:
Floïd The Genuine Aftershave 400ml
Floïd Mentolado Vigoroso Aftershave 400ml
Floïd Blue Aftershave 400ml
Floïd Mentolado Vigoroso Aftershave 150ml
Floïd Mentolado Suave Aftershave 150ml
Floïd Black (new, modern and masculine) Aftershave 150ml
Floïd Blue Eau de Toilette 150ml
The 400ml bottles are presumably made for barbers, so come unboxed. The 150ml bottles are boxed.
I have not personally tried the Genuine, so I would be interested to know how it compares to the others. I really can't tell much difference between the Vigoroso and the Suave, the Vigoroso possibly having more menthol, and initially a tad more 'aggressive'.
The Blue is very cooling and soothing, but without the obvious menthol hit of the Vigoroso or Suave, and the Eau de Toilette is absolutely top notch, in my view.
The Black is a bit too subtle for me, but certainly has it's fans.
The 150ml Vigoroso is widely available in Spain, sold in most supermarkets. The Suave and Black are a bit harder to find, generally found in Department stores or 'PerfumerÃas', though some large hypermarkets stock them too. The Blue seems to be increasingly scarce.
