Stanley Quencher H2.0 FlowState Tumbler, 40 oz, Ash
The tumbler that took over: 40 oz, a 3-position FlowState lid, a comfort-grip handle, and double-wall vacuum insulation.
A 40 fl oz tumbler in 90% recycled 18/8 stainless steel with double-wall vacuum insulation and a FlowState 3-position lid. It has a comfort-grip handle that fits the cup holder.
At 40 oz it is a large, all-day tumbler: the 3-position lid covers different drinking preferences, and the handle makes a full tumbler easier to carry. The recycled stainless steel body is the durable, reusable alternative to single-use cups.
