Product overview
For small hands and big sips.
The 10 oz. Rambler® Jr. Tumbler is a mini powerhouse. Designed to go as far as it’s taken, this ultra-durable tumbler is made with puncture-resistant 18/8 stainless steel, which means it’s always ready for rough-out-of-housing. Like all of our Rambler® Drinkware, this thing comes equipped with double-wall vacuum insulation, keeping drinks at ice-cold temperatures even when games of freeze tag go long. Plus, our splash-resistant Rambler® Silicone Straw Lid comes with a molded-in stopper to securely hold your kid’s silicone straw in place, letting you rest assured that what they’re sipping stays in their cup and off their shirt.
Note: For ages 3+, do not use the Rambler® Silicone Straw Lid with hot, carbonated, or pulpy beverages or for storage of food or perishables. Learn more about product use and safety on our Rambler® FAQ page.
