Everyday Tumbler for Cold Drinks

This 28 oz Hydro Flask tumbler uses double-wall vacuum insulation and TempShield technology to keep beverages cold for hours. The pro-grade stainless steel construction prevents flavour transfer and resists dents. A leak-resistant press-in lid with a flexible straw allows easy sipping without spills. Its cupholder-friendly shape fits most vehicle holders.

Vacuum Insulation Performance

The double-wall vacuum insulation with TempShield technology is the single specification that determines how long drinks stay cold. This design eliminates condensation on the exterior while maintaining internal temperature. No power source or active cooling is required. The stainless steel body ensures durability without affecting taste.

Simple Daily Use

The press-in lid installs in seconds and the straw flexes for comfortable drinking. Dishwasher-safe components make cleaning straightforward. The leak-resistant seal works best when the lid is pressed firmly until seated. Avoid overfilling past the shoulder to prevent pressure leaks. Not suited for buyers who need a hot-beverage thermos or a fully sealed screw-top bottle for backpack transport.
