Tropical Lime Volay | we took your basic lime to the next level. Tropical Lime is so naturally refreshing you'll think you're on a beach (and maybe you are, ha!) We wondered... why can't our beloved seltzers do just a little more for us? Well, we took matters into our own hands. Meet Volay: Club Soda's cooler cousin. With organic caffeine from green coffee beans and the equivalent energy boost of half a cup of coffee, it's the most simplistic non jittery energy enhancing beverage on the market. Still drinking boring cocktails? Vodka Soda meet Vodka Volay. Yup, Volay caffeinated sparkling water just entered the room.
