A multi-colored line with clearly distinct profiles
The Polo line has grown over the decades with several variants identified by colors (Green, Blue, Black...), each offering a very different olfactory profile rather than simple minor variations on a shared theme.
Polo Green: the classic most often cited as the reference
Polo Green (the original) frequently comes up in the line's internal rankings as the best performer and the most well-liked profile — particularly in its older formulations, actively sought after by collectors who compare different manufacturing eras against each other.
Polo Blue: the more recent, more accessible pillar
Polo Blue adopts a fresh aquatic register, opening with melon, mandarin, and cucumber notes, over a more herbaceous heart. It's a composition generally well received for its performance, without quite reaching Polo Green's cult status among more experienced connoisseurs.
