Adding to the Traveler line up is the 10oz Calcutta Stainless Steel tumbler. The Calcutta Traveler Insulated cups are built for stalking the flats, chasing fish offshore, tagging along to work or just relaxing on the beach. Even in the heat of summer, your Calcutta tumbler won't sweat. And no matter where your next adventure takes you, your Calcutta tumbler will keep your summertime beverages ice cold (and your coffee steaming hot). Calcutta Traveler mugs are double wall, vacuum sealed constructed with 18/8 Stainless Steel and are BPA free. Includes removable lid and available in 10oz. Hand wash only.
