The verdict: Yves Saint Laurent Y is the longevity pick — long (8-10h) against moderate (5-7h) for Yves Saint Laurent La Nuit de L'Homme. Yves Saint Laurent Y projects harder (strong sillage), so it owns a room — and an office can be too small for it. Character-wise, Yves Saint Laurent Y wears fresher and brighter while Yves Saint Laurent La Nuit de L'Homme sits warmer and richer. Yves Saint Laurent Y stretches into summer, which Yves Saint Laurent La Nuit de L'Homme can't cover as well.
