Stanley Quencher H2.0 FlowState Tumbler (40 oz) Review

Sold at Amazon

The cup that started the whole handle-tumbler era still gets the everyday details most right. The FlowState lid rotates between a straw opening, a drink opening, and a full cover, the comfort-grip handle makes 40 ounces feel manageable, and the narrow base actually fits a car cup holder — the trick most big tumblers still miss. Recycled stainless steel and a color wall deep enough to match anyone.

The review

The cup that started the whole handle-tumbler era still gets the everyday details most right. The FlowState lid rotates between a straw opening, a drink opening, and a full cover, the comfort-grip handle makes 40 ounces feel manageable, and the narrow base actually fits a car cup holder — the trick most big tumblers still miss. Recycled stainless steel and a color wall deep enough to match anyone.

  • FlowState 3-position lid covers straw, sip, and closed in one rotation
  • Comfort-grip handle plus a cup-holder-friendly narrow base
  • Recycled stainless construction and endless colorways
  • 40 oz is a commitment — if you mostly want coffee on a commute, look at the YETI below
