Designed to be used wherever life takes you, the Ember Tumbler does more than simply keep your coffee hot. Our largest mug yet, the 16 oz Tumbler allows you to set an exact drinking temperature and keeps it there for up to 3 hours, so your coffee is never too hot, or too cold. It features our most advanced chip ever for improved Bluetooth® reliability and a simplified pairing process. All Tumblers come with two lids, letting you choose between the leakproof Handle Lid or spillproof Sliding Lid. Made with a durable stainless steel construction, Ember Tumbler is easy to clean and is safe to submerge up to 1 meter in water. Both lids are dishwasher safe.
