The Stanley 30oz Quencher ProTour Tumbler is a large-capacity insulated drink tumbler designed for all-day hydration on the go. It features a ProTour Flip Straw lid that you can flip up to sip and snap shut to make it more leak-resistant — perfect for carrying in bags or putting in your car’s cup holder without spills. The double-wall vacuum insulation keeps cold drinks ice-cold for hours, while the stainless-steel construction is durable and dishwasher-safe. It also has a textured comfort-grip handle and a removable straw and seal that’s replaceable, making it both functional and easy to clean.
