Stanley Quencher ProTour 40oz Flip Straw Tumbler (Prickly Pear)

The Stanley Quencher ProTour Flip Straw Tumbler is a 40oz double-wall vacuum-insulated stainless-steel tumbler with a flip-up built-in straw and snap-shut leakproof lid. Constructed from 18/8 recycled stainless steel, it delivers all-day ice retention and is dishwasher-safe. The textured comfort-grip handle and narrow base fit most car cup holders, making it ideal for commutes, gym sessions, and travel. Available in vibrant summer colors (Prickly Pear, Lichen, Agave, Pink Mesa). Backed by a lifetime warranty. At $43.48, it commands a premium price but benefits from Stanley's category dominance and viral social momentum. Key caveat: the open flip-straw design carries occasional leak-when-tipped reports in community feedback, and the lid is not fully lockable like rival brands.
