Nio is a divisive citrus-green powerhouse. For some, it's the ultimate refined summer freshie; for others, an overpriced cleaning product. Expect sharp, photorealistic green notes.

Cairo Summer takes Xerjoff's Nio's neroli-bergamot brightness and cardamom-spiced heart, but the composition sits flatter overall - the photorealistic, almost glassy freshness that defines Nio is replaced with a simpler citrus-green accord, and the guaiac-cedar base loses much of the original's smoky depth.
