The legendary CK One has been a reliable resident of department store shelves for over 25 years now, and it's still being bought thousands of times a day all over the world. To some, it defines what a warm-weather fragrance should be. To others, it's the perfect post-workout refresher. To me? Eeehhhhh...it's more complicated than that. But at the end of the day, I think it's still worth your time.
The scent itself is VERY heavy on green and floral notes. Imagine something like Acqua di Gio but with a much lighter citrus accord. The bergamot, lily of the valley, and mixed greens come barreling out of the atomizer as the scent lands on your skin, with the more gentle floral notes and subtle woodiness taking their place as it dries down. Scent-wise, it's similar to a classic cologne- light, primarily citrus, meant for after a shower or shave, but it's not overly powdery or barber-shop-centric, which is why it's known as a good pick for post-workout or after getting out of the pool.
