Whether you’re a wave watcher or a wave rider, the RovR® 40 oz. Travel Tumbler is the ultimate companion for your hot or cold beverages. Crafted from food-grade 18/8 stainless steel with double-wall vacuum insulation, this mug delivers exceptional temperature retention, keeping drinks cold for at least 24 hours and hot for up to 8 hours and the ceramic lining preserves the pure taste of your drinks, keeping them flavorful for longer. With a generous 40 oz. capacity, you’ll enjoy fewer refills, while the large side handle ensures a comfortable grip. The versatile lid offers multi functionality, allowing you to sip, swig, or slurp with ease, and the included straw fits snugly into the silicone opening to resist splashes. Designed with a narrow base to fit most standard car cup holders, the RovR® Travel Tumbler also boasts a durable powder-coated finish that helps prevent surface scratches. FDA compliant and BPA-free.
