Perfect for active water drinkers, the Citrus Zinger infuses the flavor of any citrus fruit directly into your bottle. It’s not only refreshing, it’s all natural. So zing away thirst with your favorite summer flavor–oranges, lemons, limes, clementines and more. As easy as slice, press, and drink. You unscrew the bottom cup, flip the vessel onto the top cap, and press in a citrus half. Screw the cup back on…add water through the top cap opening…then shake and enjoy!
