The 20 oz (600 ml) Tumbler is constructed using double-walled, vacuum-insulated stainless steel, keeping your morning coffee or happy hour beverages at just the right temperature. It’s topped off with a tri-mode lid for flow control so you don’t spill while you chill. The heavy-duty powder coat is scratch resistant and allows you to toss the tumbler in the dishwasher when you’re finished. A non-slip silicone pad on the base grips surfaces to avoid scratches and spills. Free of BPA, BPS, and BPF.
