Eau de Guerlain is one of Jean Paul's masterpieces. As excellent as many of Guerlain's Eau de Colognes are, they have no longevity whatsoever. Eau de Guerlain is different and its ability to last seems to come from the combination of citrus and herbs. It has a very icy blast and reminds me of a long lost gem from Bourjois called Christmas in July. I haven't seen this is years - decades actually - but the scent, although very different, seemed to give the same chilled and refrigerated sensation as the Guerlain. Eau de Guerlain is an ideal scent for summer and is perfect on either sex.
