Yes, on a day out! with the insulated bottle Ellipse 900 ml / 30,4 oz in SST you will have enough to drink for an entire day of relaxing or fun and play. Fill up your bag with goodies for at the beach or for a picnic in the park. A game of volleyball, dive into the salty water and then ... ahhhh. A nice big gulp of well earned ice cold water. Even at the end of a hot summer's day, because the bottle is made of double walled stainless steel it will keep your water cool for 24 hours, right up until the very last drop. Wow! It is 100% leak proof, and can be carried along in your beach bag or picnic basket, no problem. Also great: the opening of the bottle is large enough to fit ice cubes, to make it extra refreshing! The outside of the bottle remains cool and dry no matter how hot or cold its contents. In the insulated bottle you can also carry sparkling water, so whatever your favourite drink may be; just take it along in the thermo bottle Ellipse! In order for you to enjoy your product as long as possible, we advise you to hand wash the coloured bottles. The plastic parts are dishwasher safe.
