Introducing the iconic Quencher, now with the leakproof ProTour Flip Straw lid. The 40-ounce Quencher ProTour Flip Straw Tumbler makes hydration simple — flip up the built-in straw to sip, then snap it shut when you’re done. Your water stays ice cold for hours, thanks to double-wall vacuum insulation. It’s ready to grab by the comfort-grip handle and fits in your car’s cupholder.
