This Quencher H2.0 is generously sized (but not oversized) with an easy-carry, comfort-grip handle and a narrow base that will fit most cup holders. Long day of meetings? Rowing class? Trip out of town? Our durable 30 oz tumbler comes with a straw in-built, made with recycled stainless steel, is up to the hydration challenge. The double-wall vacuum insulation will keep your water cold for 9 hours and iced for 40 hours. This Stanley tumbler is the perfect companion for all your daily activities. And to cap things off, there’s an advanced FlowState™ lid that features a rotating cover with three positions: a straw opening designed to resist splashes with a seal that holds the reusable straw in place, a drink opening, and a full-cover top.
