For keeping your drinks cold we recommend filling your bottle with pre-chilled water from your fridge. Alternatively, you can fill your bottle direct from the tap and top up with ice cubes - why not check out our own Chilly's ice cube tray - the ideal shape for our bottles!
Please note, placing your Chilly's bottle in the fridge or freezer will do nothing to change the temperature of the liquid inside due to the double-wall vacuum.
For keeping your drinks hot, we recommend filling your Chilly's Bottle with boiling water first to heat the inside. Then, empty out the boiling water and fill with a hot drink of choice.
Up to 24 hours cold is based on the water being very cold when poured into your bottle. Up to 12 hours hot is based on filling your Chilly's Bottle with boiling hot water and keeping it shut. Results will significantly vary based on the temperature of the drink put in the bottle and how many times it's opened.
