16oz All Around Tumbler

TempShield is Hydro Flask's proprietary double-wall vacuum insulation technology. It keeps your beverages hot for up to 6 hours and cold for up to 24 hours. This means you can enjoy your coffee piping hot in the morning and your iced tea refreshingly cold throughout the day, without worrying about temperature loss.

"Pro-grade" indicates that the materials and construction of the Hydro Flask tumbler are of professional quality. This means the stainless steel used is durable and designed to withstand rigorous activities, making it perfect for outdoor adventures, sports, or daily use.

Insulation in the Hydro Flask tumbler prevents heat transfer between the inside and outside of the container. This is achieved through the double-wall construction, which keeps your drinks at the desired temperature for longer periods, whether hot or cold.

The vacuum layer is the space between the two walls of the tumbler that is devoid of air. This vacuum minimizes heat transfer, ensuring that your drinks maintain their temperature. It’s a key feature that enhances the thermal performance of the tumbler, making it more effective than standard insulated containers.

The Hydro Flask tumbler is made from high-quality stainless steel, which is designed to be robust and resistant to wear and tear. This durability makes it ideal for outdoor activities like camping, hiking, or even just daily commuting, ensuring it can handle rough use without damage.

Absolutely! The Hydro Flask tumbler is designed to maintain the temperature of both hot and cold drinks. Whether you’re sipping on a hot coffee or enjoying a cold smoothie, the TempShield insulation ensures your beverage stays just the way you like it for hours.
