Bigger Adventure. Bigger Refreshment. Bigger adventures call for bigger refreshment, and our Tumbler is the perfect cup for the job. From bonfires at the beach to barbeques in the backyard, our larger Tumbler cup fits comfortably in one hand, leaving your other hand free to score that last bison burger. Plus, TempShield insulation keeps your drinks at just the right temperature, which means your frozen margaritas-or iced green teas-will stay icy for up to 24 hours and hot chocolate will stay piping hot 'til the sun goes down. The Tumblers were designed with a narrow profile, making them easier to hold and able to fit into most cupholders. The Tumbler comes with our insulated press-in lid so you can take your beverage anywhere. This lid features our Honeycomb insulation for additional temperature control. Double wall also means no condensation, so your Hydro Flask will never sweat or perspire. Hydro Flask's 18/8 food-grade stainless steel interior is non-porous and rounded corners help eliminate bacteria buildup, as well as unwanted odors and flavors. The BPA-free press-in lid is insulated to further protect your beverage from outside temperatures.
