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, 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 while the insulated Flex Cap lid prevents temperature change through convection. In addition, the inner chamber features a reflective lining for further heat retention. The result is a flask 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.
