Lacoste Challenge Refresh Deodorant Stick can be used alone or to compliment the Eau De Toilette Spray. Lacoste Challenge Refresh features a time release technology that re-activates the scent for hours after it has been sprayed, meaning you'll get a smash of reinvigorated freshness throughout the day! This technology works by trapping the top note oils & steadily releasing them to reveal a longer lasting scent.
