The Stanley Quencher ProTour is a 40-ounce double-wall vacuum-insulated stainless steel tumbler with a built-in flip straw that snaps shut for leakproof carrying. Stanley rates it to keep drinks cold for 11 hours and iced for 2 days, and the 40-ounce capacity cuts down on refills during commutes and long days outside. It sits at the top of the Quencher line: the flip-straw lid is the main difference from the classic Quencher, which uses a separate reusable straw and is not leakproof. Owners rate it highly overall, though some find a full 40-ounce tumbler heavy to carry and note the straw lid takes more care to clean than an open lid.
