I just recently discovered Joop Nightflight through an order of samples, and all I can say is; Wow! I'm loving this, and I've already ordered a big bottle. It's a super refreshing sour lemon/detergent type scent that holds those notes into an almost sparkling powder drydown. This is going alongside my Live Jazz as my go to, refreshing/exhilarating hot weather scents. I sampled Nightflight and Joop Go at the same time, and Nightflight is so much better (Go is kind of sweet & boring).
Anyway, this is a definite buy in my book, & will always be in my collection.
