Being environmentally responsible doesn't mean you should compromise on quality or functionality. The stainless steel Harmony 2-in-1 tumbler's huge 64 oz. capacity provides all-day thirst-quenching power, and double-wall vacuum insulation keeps drinks cold for hours. This tumbler features an amazing lid with two options: a lock-tight sip opening on one side and a pull-up drinking spout on the other. No compromises needed! Dishwasher safe for easy cleanup. 5.8" width x 10.8" height (spout closed).
