Whichever way your day flows, the H2.0 FlowState tumbler keeps you refreshed with fewer refills. Double wall vacuum insulation means drinks stay cold, iced or hot for hours.

Stanley has developed an advanced FlowState lid, featuring a rotating cover with three positions: a straw opening designed to resist splashes with a seal that holds the reusable straw in place, a drink opening, and a full-cover top for added leak resistance with this tumbler.

The ProTour Flip Straw tumbler lid lets you sip without worry. Just flip up the built-in straw for a quick drink, then snap it shut to prevent spills. This leakproof tumbler is ready for all your adventures.

Constructed of 90% recycled BPA free stainless steel for sustainable sipping, the Stanley Quencher H2.0 has the durability to stand up to a lifetime of use.
