Stanley Quencher ProTour Flip Straw Tumbler (40 oz)

Elevate hydration with the iconic 40-ounce Stanley Quencher, now upgraded with the ProTour Flip Straw lid—a leakproof marvel designed for worry-free sipping. Simply flip to drink, then snap it closed to keep liquids secure.

Key Features

• Leakproof ProTour Flip Straw Lid
  The innovative lid, complete with a fold-down straw and replaceable rubber seal, keeps spills at bay—ideal for tossing into bags or car cupholders.

• Superior Temperature Retention
  Keeps beverages cold for up to 11 hours and maintains ice for a full 2 days—thanks to its double-wall vacuum insulation.

• Durable & Eco-Conscious Build
  Crafted from 18/8 recycled stainless steel, offering lasting performance while reducing environmental impact.

• Comfort and Practicality
  The textured, comfort-grip handle ensures easy carrying, and its slim base fits most car cupholders. Dishwasher-safe and BPA-free for easy cleaning and peace of mind.
  Refill-Friendly Design
  The ProTour Flip Straw lid is compatible with any 40 oz Quencher body, making customization or replacement easy.
  Compact — No Sacrifice
  Despite its 40 oz capacity, the tumbler remains convenient in size—measuring approximately 10.78 in tall and 3.93 × 5.82 in wide, weighing just around 2.05 lbs.

Why It Stands Out

In tests of insulated tumblers, the Quencher ProTour emerged as an Editor’s Pick for leak-proof performance, thanks to its innovative locking straw lid—even outperforming many competitors.
