The YETI Rambler Jr. Bottle is a durable bottle for the adventurous kiddo. The 18/8 stainless steel is sturdy, the cap is leak-resistant, and it can withstand being tossed around indoors and out. The double-wall vacuum insulation keeps water ice cold (or juice!) until the last sip. The grab lid makes carrying easy, whether scrambling over rocks and roots or hanging out at the playground, with a flip-up straw for quick sips whenever they wish. Parenting is hard work, so everything is dishwasher safe when it's time for cleaning.
