This double-duty, on-the-go drink handler is topped with the Rambler Stronghold Lid, a leak-resistant, twist-on upgrade that's backed 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 Stronghold Lid is specially made for the Rambler 20 oz. Travel Mug and won't fit other Rambler Drinkware models. The Travel Mug Stronghold Lid has 4 placement options and plays nice with both righties and lefties, just like all our Rambler Drinkware. 7.5" x 2.75" x 3.5".
