**The perfect companion for all-day hydration**
The Quencher ProTour Flip Straw Tumbler is another edition to the iconic Stanley Tumbler empire. Like others from the Quencher series, this is built from 90% recycled stainless steel and constructed with double-wall vacuum insulation, which is science for: this tumbler can keep hot drinks hot for up to 7 hours, cold for up to 11 hours, and ice for a whopping two days. Where it stands out is in this completely leakproof Flip Straw Lid. This is perfect for sipping on the go and is easy-to-clean thanks to the removable spout and seal. Oh, and did we mention the comfort-grip handle and cupholder-compatible design? Say hello to your new hydration buddy.
