More than just a wine glass, Stemless is designed with you in mind. Crafted from the same high quality 18/8 stainless steel as Canteen and Tumbler, Stemless helps keep your beverage of choice cool from the first sip to the last. Its triple-insulated construction keeps your drink cold for 9 hours, or hot for 3. Whether you're sipping hot chocolate by the fire, a chilled pinot grigio with friends, or cocktails at a party, Stemless maintains your drinks' perfect temperature.
