This double-duty on-the-go drink handler is the only YETI Drinkware topped with the Rambler®StrongHold™ Lid, a leak-resistant, twist-on upgrade that’s backed with a dual-slider magnet technology. It adds a strong layer between your free-flowing drink and the outside world, come arm swings or speed bumps. And if we’re talking about where to take it, its elevated handle lets you enjoy cup-holder convenience just about anywhere. Please Note: The StrongHold™ lid is specially made for the Rambler® 20 oz. / 591ml Travel Mug and won’t fit other Rambler® Drinkware models.
