Is thirty ounces gonna be enough? Probably! Sip ice-cold water or your preferred juice for hours in the Stanley Quencher ProTour Flip Straw Tumbler - 30oz. The new ProTour Flip Straw streamlines hydration with its sip-and-snap action. This version shares a lot of similarities with The Quencher lineup, including double-wall vacuum insulation, comfort-grip handle, and cupholder compatibility.

Mix & Match: The ProTour Flip Straw lid also fits the 30oz Quencher. Nice!
