Always on the go and busy, busy, busy? Extra important to take a moment to cool off in between. A nice cool sparkling water on the train or an ice-cold sip of water on the bike? This sleekly designed Ellipse double-walled stainless steel vacuum flask keeps your favourite drink cool to the last drop. Of course, the insulated bottle will also keep all your drinks nice and warm if you want. Your favourite drink stays hot for up to 12 hours and cold for up to 24 hours. Handy tip: for extra hot or cold drinks, rinse the bottle with hot or very cold water beforehand. Of course, the outside of the bottle remains cool and dry, no matter how hot or cold the contents are. To enjoy your product for as long as possible, we recommend washing the bottle by hand. The plastic parts of the cap, however, can simply be washed in the dishwasher.
