Stanley Quencher H2.0 FlowState Tumbler 30oz
Community verdict
The Stanley Quencher H2.0 FlowState 30oz Tumbler earns solid marks for its aesthetic appeal, durable stainless steel construction, and convenient handle that still fits nicely into standard car cup holders. Most users enjoy it as a versatile daily beverage companion, though opinions remain split on whether thirty ounces is sufficient capacity for all-day hydration without frequent refills. The primary caveat noted by reviewers is that the standard straw-top lid is not entirely leakproof and can spill if tipped or inverted.

the perfect cup for winter. this is such a beautiful cup, it’s one of my favorites! pictures don’t do it justice.
I do like the handle and that it fits in a cup holder considering how big it is, though.
if you want leakproof from Stanley, I wouldn’t go with their quencher line.
I sold all my 30oz I never used them they were too small for me. BUT there are many Stanley lovers that will only buy 30.
