YETI Rambler 591ml Travel Mug. 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 talkin’ 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. 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.

Capacity 591ml / 20 US fl oz.
