Working, workouts, road trips — you’ll want this Stanley tumbler always by your side. Thanks to Stanley’s vacuum insulation, your water will stay cold for 11 hours, 4 days when iced. 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. Lastly, every piece of this stainless steel water bottle is dishwasher safe. Don't miss out on the hydration must-have you never knew you needed. 90% recycled 18/8 stainless steel, BPA-free.
