The Quencher ProTour Flip Straw Tumbler 20oz in Sorbet Gradient from Stanley is a 591ml insulated tumbler with a leakproof flip straw lid.
Flip the built-in straw up to sip, then snap it shut to toss it in your bag without spills. Double-wall vacuum insulation keeps drinks cold for 8 hours or iced for 30, the textured handle is comfortable to carry, and the base fits most car cup holders. A removable spout and replaceable seal make it easy to keep clean between refills.
