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, YETI made sure its Straw Cap (which comes included by the way) is leak resistant when closed 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+

Just the right size for little hands, the Hydro Flask for kids is made with the same stainless steel and double wall vacuum insulation as our bigger bottles. Every sip stays icy cold for up to 24 hours—so when recess or practice wraps up, the perfect refreshment is waiting on the sidelines. With a colorful, easy-to-clean Straw Lid and a durable Flex Boot this is the perfect companion for any adventure—big or small.
