The 1200ml Stanley Quencher H2.0 tumbler is made of recycled stainless steel, making this tumbler a more sustainable choice. The advanced FlowState™ lid features a rotating cover with three positions: a straw opening designed to resist splashes while holding the reusable straw in place, a drink opening, and a full-cover top. Thanks to the vacuum insulation, the beverage will stay cold for 11 hours (48 hours when iced). The ergonomic handle has comfort-grip inserts for easy carrying, and the narrow base fits most car cup holders. Recycled stainless steel.
