Stanley Quencher H2.0 40oz Tumbler with Flowstate Lid

The Stanley Quencher H2.0 40oz is a vacuum-insulated stainless-steel tumbler with double-wall construction that keeps drinks cold for 24+ hours or hot for 12+ hours. Features a rotating 3-position Flowstate lid (straw, flip, or handle sip modes), 18/8 stainless steel body, and a cup-holder-compatible base. BPA-free and top-rack dishwasher safe. Available in multiple colorways including Tigerlily. The open-straw design and lightweight construction make it ideal for everyday carry, though some users report occasional lid leaks if tipped. The viral 40oz size has dominated social media and outdoor-gear communities, driving exceptional demand despite premium pricing.
