CK One Summer 2017 is a crisp, unisex summer fragrance with a strong emphasis on citrus, ozonic notes, and a sharp, peppery green accord. It opens with a bright burst of citron, lime, and cucumber, delivering a clean, refreshing, and linear scent that resembles a freshly laundered linen beside the sea. The middle notes of ginger, pepper, saffron, and white pepper lend a spicy, masculine edge, though the cucumber is noted as fleeting or overwhelming by some. In the base, guaiac wood and musk add a subtle, soft warmth that anchors the fragrance without being sweet or heavy. It performs best in warm, dry climates and is ideal for daytime wear during summer months, offering moderate longevity and a sillage that tends to be intimate to moderate. Many users find it refreshing and inoffensive, suitable for work or casual outings, and appreciate its clean, easygoing character. While some critics describe it as synthetically sharp or smelling like cleaning products, others praise its authenticity, longevity in fabric, and suitability as a lightweight, universally wearable summer scent.
