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.
