The YETI Kids' Rambler® Jr. 12 oz Bottle is a small-and-mighty kids bottle over-engineered for your little wild ones. This 12 oz powerhouse features double-wall vacuum insulation that locks in ice-cold water through backyard campouts and breaks between tag. As a well-deserved convenience for you, its Straw Cap (which comes included) 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 accidental bumps and drops.
