Forming two of the most popular scents in their collection, Calvin Klein In2U mixes fresh and floral notes to create an easy-to-wear fragrance that lasts all day long. The In2U perfume and the In2U aftershave are one and the same, just like the ground-breaking CK One. Combining pink grapefruit and sugar orchid with amber, red cedar and vanilla, it’s the perfectly crafted fragrance for him and for her.
