Drynk is the beverage tumbler that takes flexibility to new heights. Inside the slim, stainless steel body, vacuum technology keeps coffee hot for up to 12 hours and water or soda cold for as long as 18 hours. The bottom features a built-in anti-slip coaster but that’s not all. Each comes with two interchangeable lids. The Sipper boasts a magnetic latch that keeps the lid open as you drink — no more bumps on your nose. The Gulper is a wide-mouth design, perfect for guzzling down sports drinks or for pouring into the twin cups — also included with each Drynk.
