A really nice amber. It's heavy on the benzoin, so there's an old fashioned baby powder quality to it that keeps it from feeling too syrupy or smokey. Instead, it's "perfumey" in a classic way, like one of those amber balls in grandma's closet. There's also a nice dusty sandalwood supporting the benzoin, and a pinch of vanilla and a cozy frankincense drydown for warmth.
I ended up buying a travel size of this and I'm quite enjoying it in the cold weather. My tastes usually run towards dark smoky resinous ambers, but Kalimantan is such a perfect expression of benzoin in all its powdery matronly glory that I'm really happy with it even if it isn't what I usually enjoy.
