40 Knots is one of the most surprising fragrances in my collection. When you hear the name and see the bottle, you immediately assume it's going to be a fresh summertime ocean scent. And with all of the designer and budget fresh summer offerings, what is the point of paying niche prices for an aquatic fragrance? Thankfully, 40 Knots goes in a completely different direction, giving you more of a woody-amber fragrance with some saltiness at the top. It's so beautifully blended and is one of the most luxurious smells I have ever experienced. I love how much depth this fragrance has and how it develops differently every time I wear it. Sometimes it's this fizzy coca-cola smell, sometimes it's this clean and powdery babywipe like smell, while other times it has this luxurious creamy woody(sandalwood?) scent with some crisp airy saltiness coming through. I absolutely love wearing this one since I never know how it's going to come across that day. Longevity and projection are excellent on this one, easily going for 8-10+ hours on my skin with a louder projection. And I'd say it is safe to wear any season and time of day, but I would ease up on the trigger on the more scorching days. As far as Xerjoff fragrances go, this is definitely one of the safer mass appealing options that you can go with. It's up there with my top 3 Xerjoff scents along with Monkey Special and Torino21.
