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. Its included straw cap is leakproof 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. Features Dishwasher safe. 18/8 stainless steel. Double-wall vacuum insulation. Leak-resistant cap. Please 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. Please Note: Rambler® Bottle Straw Cap is leakproof when closed, but is not packable as the straw cap can open if pack is shaken or jostled.
