Stanley Quencher H2.0 FlowState Tumbler

8.2 / 10 · From ~$45

8.2

The Quencher H2.0 is a 40oz double-wall stainless tumbler with a handle, a rotating three-position lid, and a reusable straw. It shines at exactly one job: keeping a huge volume of iced water cold for hours while staying easy to sip at a desk or in a car. The honest knock is that it is not leakproof - tip it over with the straw in and your laptop bag will find out. The 40oz size also fights with many cup holders, and you are paying a hype premium over near-identical competitors. Buy it if you genuinely drink that much water and live at a desk; skip it if you need something that seals shut in a backpack.

Why we rate it

Excellent ice retention - drinks stay cold through a full workday
Comfortable handle makes the big size actually carryable
Three-position FlowState lid covers straw, wide-mouth, and closed sipping styles

Keep in mind

Not leakproof - tips and spills through the straw opening
