Can Chilly's Series 2 Bottles keep drinks hot?

Yes Chilly's Series 2 Bottles can keep drinks hot for up to 12 hours. We recommend for best results filling your Chilly's Bottle with boiling water first to heat the inside, then emptying out the boiling water before filling your bottle with a hot drink.

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.
