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 leak-resistant when closed and both the bottle and cap are dishwasher safe. Plus, your insulated kids water bottle is engineered with a super strong, stainless-steel armour that can handle taking a tumble. This carefully designed reusable drink bottle is all about complete hydration for your little one. Note: For ages 3+. Do not use the Rambler Bottle Straw Cap with hot, carbonated, or pulpy beverages or for storage of food or perishables. Learn more about product use and safety on our Rambler FAQ page.
