Aldehydes and coconut water form the top notes, a sparkling, faintly creamy freshness. The base notes of amber, cashmeran and sandalwood take over, smooth and woody rather than sweet, with musky and powdery character, a hint of white floral and a soft balsamic glow. Men and women wear it alike, and it suits anyone who wants a bright start that mellows into calm. Voters choose it in summer and spring, and it moves easily from day into evening and night. The longevity vote leans long lasting, while the sillage vote clearly lands on moderate. A 10ml decant lets you live with it through a season and see how the coconut water opening gives way to the woods. ## Decant sizes - 3ml: €14.58 - 10ml: €47.70 Ships within 1 working day ## Frequently asked questions ### Shipping and returns We ship across the EU.
