Constructed of recycled stainless steel for sustainable sipping, our 40 oz tumbler offers maximum hydration with fewer refills.Thanks to Stanley’s vacuum insulation, your water will stay ice-cold, hour after hour. 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. The ergonomic handle includes comfort-grip inserts for easy carrying, and the narrow base fits just about any car cup holder.
