The Yeti Rambler® Jr. is a small-and-mighty kids’ bottle over-engineered for your little wild ones. This 12-ounce powerhouse inherited double-wall vacuum insulation from its Rambler® Drinkware predecessors, carrying on the family legacy by locking in ice-cold water for backyard campouts and breaks between tag. We made sure its included straw cap is leak-resistant when closed and both the bottle and cap are dishwasher safe. Plus, it’s engineered with a super strong, stainless-steel armour that can handle taking a tumble.
