The Stanley Quencher ProTour Flip Straw is a 40oz double-wall vacuum-insulated tumbler in Rose Quartz that keeps drinks ice-cold for hours. Built from 18/8 recycled stainless steel with a leakproof flip-up straw lid, it features a textured comfort-grip handle and a narrow base that fits most car cup holders. Dishwasher-safe and BPA-free, with a lifetime warranty. The ProTour variant improves on the original H2.0 with a redesigned flip-straw mechanism and softer handle. Ideal for commuters, gym-goers, and outdoor enthusiasts who want iconic Stanley durability and insulation without the hefty price of premium brands like Yeti.
