Ultra-durable so your little wild ones can have ice cold water of their own. 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.
