The 10 oz. YETI® 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 YETI’s 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, YETI’s splash-resistant YETI® Rambler® 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. Silicone splash-resistant straw lid: Keeps big sips from turning into bigger spills Cup holder compatible: Fits in most car seat cup holders to copilot your kid’s adventures. Double wall vacuum insulation: Holds the cold wherever you take it. Dishwasher safe:  Because no one needs more work to do.
