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 talking about where to take it, its elevated handle lets you enjoy cupholder convenience just about anywhere.

Please Note: The Stronghold Lid is specifically made for the Rambler 591mL Travel Mug and won’t fit other Rambler Drinkware models. The Travel Mug Stronghold Lid has four placement options and plays nice with both righties and lefties, just like all our Rambler Drinkware.
