A scaled-down version of the legendary YETI water bottle, the Rambler Jr. is a perfect match for rough-and-tumble kids. Its armor-like stainless-steel construction can take a tumble on the playground without so much as a ding. Double-wall vacuum insulation keeps kids' drinks icy cool all day, a built-in straw makes it easy to sip, and the leakproof lid eliminates backpack accidents.
