TAKE YOUR MORNING COFFEE TO-GO. This double-duty, on-the-go drink handler is topped with the Rambler StrongholdTM Lid--a leak-resistant, twist-on upgrade that's back with dual-slider magnet technology. This lid easily rotates to fasten for both right- and left-handed users, adding a strong layer between your free-flowing drink and the outside world. And if we're talkin' about where to take it, its elevated handle lets you enjoy cupholder convenience just about anywhere. Please Note: The StrongholdTM Lid is specially made for the Rambler 20 oz. Travel Mug and won't fit other Rambler Drinkware models. The Travel Mug StrongholdTM Lid has four placement options and plays nice with both righties and lefties, just like all our Rambler Drinkware. Do not use the Rambler Travel Mug StrongholdTM Lid with carbonated beverages or for storage of food or perishables.
