Hi, good fragrances for men with spearmint note, if is possible basenote
Spearmint?
Omnipotato
Spearmint oil and its constituent aromachemicals (most notably menthol) are very volatile, meaning they will evaporate quickly and last for a short time, so it would be difficult to achieve a minty base note. That being said, I think the best spearmint fragrance would be Enclave. Eros Eau de Parfum has a decent minty freshness too but it is not as potent and prominent as Enclave.
Sedley has an addictive Spearmint note that sticks around for a fair amount of time on my skin for a top note. Very refreshing summer aquatic scent !
Heeley menthe fraiche
I'd say either Menthe Fraîche or You Or Someone Like You, though as Omnipotato very clearly said mint scents tend to fade quickly to leave the spotlight to middle and base notes, and I can't think of any fragrance where mint lasts very long.
I like Aqua Allegoria Herba Fresca but it's not really sharp. And Saint Julep but this is more dusty patchouli to my nose.
