Channel summertime vibes and memories of young love with the Watermelon Moonshine Quencher. Our exciting collaboration with a country superstar features the 40 oz Quencher H2.0 FlowState Tumbler in a juicy, pink watermelon hue paired with fresh green details reminiscent of a watermelon rind. Whether hydrating on the gate of a pickup truck, in the kudzu vines or on your front porch—you’ll want this tumbler by your side. Constructed of recycled stainless steel for sustainable sipping, our 40 oz Quencher offers maximum hydration with fewer refills. Thanks to Stanley’s vacuum insulation, your watermelon moonshine (cut the burn with a little lime) or other favorite summertime beverage will stay ice-cold, hour after hour. The advanced FlowState lid features a rotating cover with three positions: a straw opening designed to resist splashes while holding the reusable straw in place, a drink opening, and a full-cover top. The ergonomic handle includes comfort-grip inserts for easy carrying to your weekend picnic, and the narrow base fits just about any pickup truck cup holder.
