YETI Rambler Jr. is a small-but-mighty children\'s bottle that has been over-engineered for your wild ones. This 12 oz. powerhouse inherited double-wall vacuum insulation from its Rambler forefathers, carrying on the family tradition of keeping ice-cold water locked in during backyard campouts and school breaks. Made from a super-strong stainless steel armour that won\'t flinch in the face of bumps and drops, even though when they have slippery hands. To view more of our YETI accessories, press here.
