Rambler Jr. is a small-and-mighty kids bottle over-engineered for your little wild ones. This 12 oz. powerhouse inherited double-wall vacuum insulation from its Rambler predecessors, carrying on the family legacy by locking in ice-cold water through backyard campouts and breaks between tag. As a well-deserved convenience for you, its Straw Cap (which comes included by the way) is ultra leak-resistant and both the bottle and cap are dishwasher safe. Plus, it’s engineered with a super strong, stainless steel armor that won’t flinch through bumps and drops on account of slippery hands. For ages 3+ Outside Dimensions: 8 1/4" × 3" Empty Weight: 16oz. DISHWASHER SAFE: Because one less chore sounds nice. 18/8 STAINLESS STEEL: To withstand all dents and drops.
