Vacuum-insulated stainless steel bottle | Kalsten

The drink is lukewarm even before half has been consumed.

Those who drink a lot on the go know the problem: The coffee in the morning is cold after an hour, and the ice water in the afternoon has long warmed up. This double-walled vacuum drinking bottle made of stainless steel keeps hot drinks warm for up to 24 hours and cold drinks fresh for the same duration – whether during sports, traveling, or at work. Once the bottle is filled, you don’t have to worry about the temperature of your favorite drink all day.

Advantages

• No more lukewarm drinks on the go: Thanks to double-wall vacuum insulation, the temperature remains stable for hours – no cooling down, no warming up, no compromise.
• No annoying refills in between: With volumes ranging from 500 ml to 1500 ml, one filling is enough for the entire day – less stress, fewer interruptions.
• No worries about rust or condensation: The inner and outer walls made of stainless steel protect against corrosion, and the insulation prevents sweat water from forming on the outside – the bottle stays dry on the outside.

Application

1. Fill: Fill the bottle with the desired drink – hot or cold – to the desired amount.
2. Close: Screw the lid tightly to ensure that the vacuum insulation works optimally and no heat escapes.
3. Take along: Place the bottle in a bag, backpack, or cup holder – the drink stays at the right temperature throughout the day.

Pro tip: If you use the bottle for hot drinks, fill it briefly with hot water before filling it with the drink and pour it out after 30 seconds – this pre-warms the inner wall and significantly increases the insulation performance.
