A good insulated bottle keeps water cold for up to 24 hours and tea or coffee hot for up to 12 hours – no electricity, no ice cubes. Double-walled vacuum-insulated bottles from SIGG, Yoko Design, Black+Blum and Carl Oscar. BPA-free, leak-proof, from a Swiss warehouse.

How does a vacuum-insulated bottle work?

Two stainless steel layers with a vacuum in between – since a vacuum does not conduct heat, the temperature inside remains stable. Cold drinks stay cold, hot drinks stay hot.

What to look for when buying?

Opening

Narrow opening (approx. 38 mm) for on the go. Wide opening (53 mm+) for soups, ice cubes and easier cleaning.

Size and weight

0.5–0.75 L for the office and school. 0.75–1 L for sports and tours. Stainless steel is heavier than plastic – but durable and taste-neutral.

Closure type

Screw cap is the tightest. Sports closure is more practical on the go. Many models combine both.
