Fresh. Provocative. Unapologetic. The intense fragrance for all. Calvin Klein CK One Essence is twice as concentrated as the original icon. Crafted with premium, certified responsibly sourced ingredients, CK One Essence features top notes of sparkling Italian bergamot and blood orange that add vibrant intensity to the fragrance. Organic green tea accords are drenched in a warm base of natural sandalwood and upcycled musk. The feeling is clean and sensual. A recyclable bottle with a modern translucent metallic finish.
