The Ember Cold Tumbler is a 16 oz insulated cup for cold drinks, built with a glass interior and a metal body and fitted with a handle. Its glass lining is the draw: unlike stainless-steel rivals, it does not hold onto flavors or leave a metallic taste, so water, iced coffee and cocktails all taste as they should. The trade-off is weight and fragility compared with a plain double-wall steel tumbler, and it does not keep drinks hot. It suits people who sip cold drinks slowly through the day and care more about clean taste than about rough handling.
