Whether you're taking your morning coffee to the office, hiking through the mountains or simply heading to the gym, Hydro Flask's TempShield™ double-wall vacuum insulation ensures your beverage of choice tastes exactly how you want it to, for as long as you need it to. A double-walled inner and outer chamber within the flask creates a vacuum to prevent heat transfer through conduction, whilst the Straw Cap makes taking a sip on the go simple and easy.

In addition, the inner chamber features a reflective lining that deflects radiation, ensuring there's virtually no way heat can escape or enter the flask. The result is a flask that is unrivalled in its ability to ensure optimal temperatures for your drink of choice; staying cold for up to 24 hours and hot for up to 12 hours.

The Hydro Flask 21oz Standard Mouth water bottle has a removable, Straw Cap and carrying loop for ultimate portability and easy-carry convenience. The circumference of the standard mouth design is effortlessly able to accommodate ice cubes to give your beverage that extra chilled factor on long days.
