Tonka is a remarkably focused accord of... Tonka! Surprise! However, with the smattering of other Tonka frags I have, I am left wanting more out of Esteban. The good news is that if you hang in there for a longer ride, Tonka's dry down is a glorious comforting skin scent. This leads me to think of it as either a skin scent, or a layering scent. But for $100 bottle, it's pricey for it's singularity. It's positively unisex, not femme.
The comparisons hit from everywhere... Azzaro pour Homme by Azzaro, Jicky by Guerlain, Carven Homme, Tam Dao by Diptyque, Ange ou Demon by Givenchy, Jacomo De Jacomo Rouge By Jacomo, Musc Ravageur by Frederic Malle, Fumerie Turque by Serge Lutens.
Every single one of these other fragrances is remarkably constructed with sophistication and complexity. Tonka is decisively not.
